The Igor worked great. I had a heck of a time trying to order lights for the trailer - either not getting the ones I intended getting or mismatched lights. But you came through like me a champ. Thanks.
by: Theodore02/16/2020
This one is for the “driver” side. It has the lens on the bottom for lighting the license plate. (It does not include the license plate holder. I like this one because you just push in the wires. I recommend this light.

No worries

Great Product, it's good quality and will fit perfectly for the trailer I use in my Air Conditioning, Heating & Refrigeration Business. The only problem is I ordered the wrong side. Wasn't sure if by the which one was the left or the right? I was looking at the trailer form the front when I determined it was the left one but it appears your suppose to look at the back of the trailer when you do that. Guess I will be ordering the otherside here shortly. Maybe I can get an exchange or if not then I will have a spare and hope if it does get broken again it's the other side. Etrailer has some really good quality stuff at a very good price. I got my hidden hitch from them at a Great Price. They even had a video that showed me how to install it. A couple of the local places here wanted 3 times the amount of what I paid to provide the hitch and install it for me. Will never go anywhere else for any trailer parts or accessories.

Great job etrailer.com!

We purchased a replacement combo tail light. It arrived on time, in good condition and was the exact replacement.
Although it does not really show on our trailer, we have attached a picture since the trailer has a unique use. It's a small landscaper's trailer converted to a mobile radio broadcasting studio.

Last project built. Used etrailer for almost all parts, including the taillight. Friend wants one now so started another one. I will be getting all the parts from etrailer...

These light were a good replacement set for my Home Depot Snowbear trailer taillights. Best price I found for this or similar was here at etrailer.com.
Pic is not of my own trailer but is the same model. You can see the configuration of the taillights.

The item I ordered came quickly and was exactly what was ordered and was an exact fit to replace the damaged light on my camper. etrailer filled my order quickly and shipped the item promptly and followed up with tracing information. I wouldn't hesitate to purchase products from them again.
by: jes07/12/2015
I ordered both the ST9RB and ST8RB. After years of use, my other boat trailer lights were starting to cause me problems. I decided to order new ones for each side. These are a different make, but the connections were the same as were the mounting holes. Just took minutes to mount and both worked great. Nice bright lights again! Good price and fast shipping. I would definitely order again.

Other than changing a bulb, they are still working like new! Money well spent.
by: Jim B09/30/2014
Lights were a perfect replacement for existing (busted) trailer lights. These lights did not contain wires, but had well-marked jacks to insert existing wires into. Installed in less than 30 minutes, tested - working great.

After a year, lights still working great. They stay out in elements year-round.
by: Larry H.03/31/2014
etrailer.com had exactly what I needed. I bought a replacement for a broken trailer stop, turn, tail and license plate light for my bar-b-que trailer and it matched the other side perfectly. It was packaged very well. I'll be a repeat customer.

Great company!
I received my order promptly, unfortunately the box and contents had been smashed during shipping. After contacting customer service via e-mail, e-trailer arranged for a replacement in no time. I will definitely buy from you again when I'm in the market for trailer parts.
Thanks e-trailer!

After a year of use of our trailer hauling hay, we moved and used our trailer for some of our belongings, 1700 miles in the rain, and all the trailer lighting still works perfectly. Thanks again etrailer.

Great replacement
by: Bob R10/30/2016
Exactly what I needed to replace broken tail light on my trailer. It was an exact match so was able to salvage some parts from old one ... just in case. As I recall, the price was fair and delivered in good time.
I have no complaints ... only praise.
Would highly recommend.

Last I used the trailer the signal lights were good as new. Should I need quality replacement parts in the future I would not hesitate to place my order with etrailer again.Thanks for making it affordable and easy.
by: John S.07/30/2014
Item arrived quickly and was well packaged. It is an easy install, simply strip the end of your trailer wires and feed them into the appropriately labeled spring contact (Stop / Turn or Tail ) that will automatically seat the wire in place. Removal of wire is done by using something like a toothpick to push on the spring contact thru a small hole below the wire to relieve tension and slip the wire back out. Like some speaker connections. Both lights worked first time.
by: Mr jewell05/22/2016
product was shipped and arrived on time. lights were a match for the ones replaced. oem lights had problem with sockets , bulbs would lose contact.
after a year these have work and held up great. I give etrailer a a+ rateing.
web site, price, service and a good company to use AND I WILL CONUINE TO.

NO PROBLEM, GASKET STILL WATER TITE. OEM HAD TO CLEAN INSIDE ABOUT EVERY 3 MONTHS, PLUS MOISTURE ALWAYS SHORTING BULBS. BEST LITE EVER USED AND TOP SUPPLIER
by: Dr. Bob M03/12/2017
Quite happy. Ordered trailer lights. However the supplied wireing was to short end after installation came apart requiering takedown and 're do
If your supplier could add 1 or 2 inches to the wires would make a great difference
by: Bloody Knuckles10/05/2019
They WORK!! After trying to retro-fit some old taillights I had laying around, I bought and installed these on my trailer. I should have my head examined for not starting out with these lights for the solution to my situation.
by: Marc b07/11/2014
Great service. I am a diy er. Was refurbishing an old trailer. Never done that before. Rewired but could not get lights to turn on when the car brakes Applied And car lights on. Took me forever to figure it out but FYI...if you have a tilt trailer...the tilting part needs to be connected to the main part with a ground..... :)..... Learned that on this site. Also bought lights here. Great service. Love the videos on specs. Very helpful. Will look and buy here first next time.

See what our Experts say about this Optronics Trailer Lights
- Trailer Stop, Turn, Tail and License Plate Light Connection Not Staying StrongWe recommended stripping the wire 1/4 inch and pushing through the hole. If this does not work and the wire keeps releasing, it may be faulty. Do not attempt to solder the wire. You may call us at 1-800-298-8924 for further assistance.
view full answer... - Replacement Bulb for Optronics 7-Function Trailer Light # ST9RBIt looks like you are are using Optronics 7 function trailer light # ST9RB, which you referenced. The replacement bulb for this light is # A1157B. The Optronics replacement bulb, # A1157B , is a dual filament bulb. The double-filament design works for combination brake, tail and turn lights.

view full answer... - What Does Shock Proof Socket Mean for Trailer Lights?As you mentioned, some of the trailer lights like the Optronics Trailer Stop, Turn, Tail and License Plate Light, 7-Function, Left Hand # ST9RB state that they have a shock proof socket. The manufacturer specifically makes the housing so that the socket has a little bit of play for vibration and road shock built in and they term that a shock proof socket. It just ensures the socket isn't mounted so rigid that the bulb has no give and shatters. This vibration dampening design helps the...
view full answer... - The Optronics Trailer Light, # ST9RB, Is Not Working On Trailer Lights With Separate Ground WireThe Optronics Trailer Light, # ST9RB is a stud mount light that is grounded through the mounting studs. The lights on your trailer are using a separate ground wire. You will have to run a ground wire to the stud to be able to ground the light. I have the Optronics Trailer Light, # STL9RB. This is a same size light with the same features, but has LED lights instead of the incandescent lights. It is not grounded through the studs so it has the three wires ( brown, yellow, and white) like...
view full answer... - Is Bulb Already Installed on Trailer Stop, Turn and Tail LightYes, the Trailer Stop, Turn and Tail Light, 6-Function, Right Hand # ST8RB does come with the bulb installed. The matching light for the left side of your trailer is the Trailer Stop, Turn, Tail and License Plate Light, 7-Function, Left Hand # ST9RB, which also has the bult installed.
view full answer... - How to Wire Optronics Right-Hand Trailer Stop, Turn and Tail Light, Part # ST8RBThe Optronics Right-Hand Trailer Stop, Turn and Tail Light, Part # ST8RB, connects with two wires. On the rear of the housing are holes to accept bare wire and underneath each one is a smaller hole that serves as a wire release; just insert a small pin (or something like a paper clip) to release the wires. The left-hand matching light is part # ST9RB. If you refer to the included photo illustrating a trailer-side 7-way connector you will be able to see which two wires from the connector...

- How to Connect Trailer Wiring to Optronics # ST8RB and # ST9RB Trailer TailllightsIf you have the Optronics # ST8RB and # ST9RB, no connector is needed. On the back of the taillight, there is a hole for the stop/turn and a hole for the running light wire. Each of these holes will have a smaller hole directly below it. Strip back the insulation on the wire by about a 1/4 inch, twist the copper strands of each wire tightly and push it into the hole in the back of the lamp as you're pushing a small screwdriver into the smaller hole. Once the wire is fully inserted, remove...

- How To Connect Optronics Trailer Lights # ST8RB and # ST9RB To a TrailerThe quick connect feature on the Optronics Light, part # ST8RB, and part # ST9RB, means that you can connect the wires by inserting them into the four holes on the back of the light. It is not referring to a separate part. The wires would be stripped about 1/4 inch and pushed into the correct hole on the back of the trailer light. The holes are marked with the tail light function that the hole provides. The wire when pushed in the hole will automatically lock in place and give you a quick...
view full answer... - Locating Left Side Assembly for Optronics Trailer Light # ST8RBThe Optronics Trailer Stop, Turn, and Tail Light # ST8RB referenced in your question is for the right side of the trailer. For the corresponding Left Hand assembly, you will just need part # ST9RB, which also includes the needed license plate light. These are really nice, red square trailer lights that are corrosion resistant and feature a replaceable lens and bulb. I have attached a couple short video demonstrations on these lights, along with an installation video that you might find...
view full answer... - Is the Optronics Tail Light # ST8RB Compatible with 3 Wires for Trailer Light FunctionsThe Optronics tail light part # ST8RB that you referenced actually doesn't come with any wiring at all. The back of the assembly has holes in it for quick connecting of your light functions. Simply insert the stripped wire into the appropriate slot. This is the passenger side light assembly. For the driver's side assembly you will need part # ST9RB. Attached are some reviews videos and an installation video for you to reference.
view full answer... - Does Optronics Tail Light Lens A90RB Include a Clear Portion for a License Plate LightThis lens is meant to be used as a replacement to the Optronics tail light, part # ST90RB. It does not have a clear portion for a license plate light. You are looking for a light like Optronics part # ST9RB or part # STL9RB. You could also use Optronics part # ST17RB. I have linked to these parts below.
view full answer... - Difference Between Optronics Left Hand # ST8RB and Right Hand # ST9RB Trailer Lights It sounds like you are referring to the Optronics Right Hand Trailer Light # ST8RB and the Left Hand # ST9RB. The only difference between the two assemblies is that the Left Hand/Driver's Side unit features an additional license plate light to illuminate the trailer's license plate. I have attached a couple short video demonstrations on these lights that you can also check out.
view full answer... - Replacement for Old Trailer Square Tail Light 4-5/8" x 4-5/8"I might have an option for you but without more detail, like a photo, it would just be a guess. That said, the size you mentioned is pretty common more or less for square trailer tail lights like the Optronics Combination Trailer Tail Light part # ST8RB for passenger or part # ST9RB for driver. If this is what yours looks like, I recommend using these as the two stud mounting pattern is pretty standard so don't get bogged down in the small dimensional differences. In regards to a replacement...
view full answer... - Replacement Square Stud Mount Trailer Lights for Utility TrailerThe Combination Trailer Tail Light part # ST9RB for driver side or part # ST8RB for passenger side is just what you need to replace the tail lights on a utility trailer. The lights mount via two studs which are 2" apart so they will be a direct replacement. In regards to installation, the lights ground though the studs so you only need to attach the stop/turn and running light wires for each side.
view full answer... - Are the ST8RB and ST9RB Submersible LightsI have a solution for you, but neither the # ST8RB nor # ST9RB are submersible lights. Instead, you'll want to use the # ST6RB and # ST7RB - which are the submersible versions of those lights. These are still incandescent tail lights that look exactly the same, have the same dimensions and are the same 2 wire electrical system, they're just sealed up so that they can be safely used on boat trailers.
view full answer... - Replacement Left Taillight for a 2006 8000HD Snowbear Utility TrailerI pulled up a couple pictures of a 2006 8000HD trailer by Snowbear and it looks like the correct taillight you would need is the # ST9RB.
view full answer... - Recommended Replacement Trailer Lights With Side Lights For Small Utility Trailer We have just what you are looking for. I recommend the LED Submersible Trailer Stop, Turn and Tail Light, part # STL8RB. This is for the right side of the trailer and is a stud mounted LED light. It has the side marker light that illuminates when the running lights are powered. For the left side of the trailer you will want part # STL9RB. I have attached a product review video and have also attached a drawing that shows the dimension for these lights you can take a look at.

- Replacement Trailer Taillight Lens for Optronics Trailer Taillight # ST9RBWe do have replacement lenses for the Optronics trailer taillight # ST9RB that you referenced. For that you'd just need the # A8RB this would be the easiest solution.
view full answer... - Installation of Bulb in Optronics Trailer LightThe Optronics Trailer Light # ST8RB for the right hand side and # ST9RB for the left has a shockproof socket for the bulb to insert into. The replacement bulb is # A1157B.
view full answer... - Is There More than One Bulb in Optronics ST8RB and ST9RB Trailer LightsFor the trailer lights # ST8RB and # ST9RB there is only one bulb inside the housing and it is a 1157 like you mentioned. For a replacement you would want the part # A1157B. The light from the one bulb lights up the side and the front of the assembly.
view full answer... - Installation Method for Optronics 6-Function Trailer Stop, Turn and Tail Light # ST8RBThe Optronics 6-Function Trailer Stop, Turn and Tail Light # ST8RB that you referenced does not require a bracket for installation. This light is of the type that uses the two threaded mounting studs, spaced 2-inches apart, to attach to your trailer. These mounting studs also serve a second purpose; they provide the ground connection to complete the electrical circuit. Please refer to the linked video. Certainly if you wanted to mount these with a bracket you could use a simple L-bracket...
view full answer... - Replacement Tail Light Lens For Optronics Combination Trailer Tail Light # ST9RBThe Peterson Lens # 440-15R will work as a replacement for the Combination Trailer Tail Light # ST9RB. The holes for the lens are slightly different so the bolts will sit differently on the Peterson lens as it is not bored to flush mount the lens screws for your Optronics lens.
view full answer... - Recommended Replacement LED Lights For Trailer That Keeps Blowing FusesThe wires with the circuit you are using are not big enough to handle the draw you have so increasing the fuse is not recommended. I recommend replacing the lights you have with LEDs. The replacement for the # ST9RB lights you have now would be part # STL9RB. These draw about 1/10 of the amperage draw the # ST9RB does. This would decrease the draw on your system and a larger fuse would not be needed. Occasionally when LED lights are installed you will have what is called hyperflash,...

They are still on and I assume they are still working. Parked the trailer in storage after I put the lights on and have only been out to put the new license plate sticker on.
