Optronics STL42 Series 4 Inch Round LED Light with Mounting Flange Diagram

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

After ordering July 11th and a roundtrip from Missouri to L.A. to Keswick Ontario, Canada we received the shipment July 25th. Tailights fit my 2006 Ranger trailer perfectly. Thanks to Paul for tracking my shipment when it didn't arrive on the originally scheduled delivery date and keeping me updated.

Product is perfect and quick shipping.



by:

The trailer tail light fit perfectly on our 2011 Montana camper.
I would purchase the lights again!!



by:

Used these to replace old lights on my horse trailer. Installation was easy and they are very bright. I had issues with a connector on my first order, but the second was just fine. I also had issues with one being dim, but found out it was my trailer plug. Once it was replaced, it was great! Would use these on another trailer if needed.

Light fit perfectly on my trailer and got here Amazon fast.

I always find the right parts for my boat trailer. The service is great I like to keep a spare set of lights for my2008 Ranger trail trailer

I put these LED lights on my 1967 Scotty. They have a nice clean look, and show up so much better than the originals. The wiring process, with the plug in connections, was easy!

Great lights, very bright and visible day and night, much much better than the factory bulb light. I have recommended them to our friends who have RV's
Thanks etrailer



by:

Thanks... the light is perfect and at a great price. The other place wanted $26.00 for the same light and you charged much less. I highly recommend etrailer.com for parts.



by:

Perfect fit, wiring as described! Perfect upgrade for our 60s Sears Tent Trailer



by:

100 times better than the original lights I had with traditional bulbs. With the LEDs you can see them even better during the day. Which is nice to know that people can see me at all hours of the day.



by:

it has been doing fine with no problem



by:

Shipping could be faster



by:

They look great and are plenty bright. Don't forget to get those wiring pigtails though. These do not have any way to connect without them. No external wires, just a 3-prong connection on the housing.

  • Replacement Taillights, Wiring and 7-Way Connector for Car Hauler
    To fit the round 4-1/2 inch holes on your trailer for the rear brake lights you could use the # STL42RB as this will fit in that hole. For a pigtail harness you would also need # A45PB. For the side clearance lights you would need to enlarge the holes to 3 inch in diameter, use the # A55GB as a grommet and then use # MCL59AB for the lights and # A46PB as a wiring harness. For a replacement 7-way with 8 feet of wire for running new wire everywhere you would want the part # H20046. You...

  • Is there a Trailer Tail Light that Matches Peterson Back Up Light # 411SC
    We do not have an exact match for a red round tail light like the Peterson Back Up Light, # 411SC, that you have referenced that is a flange mount. The closest flange mounted lights are going to be the Peterson round tail lights # 431800 and # 432000. For a flush mounted light, you could use # 429800 which may be more what you are looking for. We also have the Optronics brand flange mounts # STL42RB or # ST47RB. They use wiring harness # A45PB.

  • Replacement LED Trailer Light to Reduce Power Draw
    The Optronics LED Trailer Light # STL42RB is not what I could call an exact replacement for the # ST40RB but for all purposes it will be what you're looking for. The # STL42RB is 1/8 inches larger in diameter and 3/8 inches deeper so at the most you may need to do a little filing to the opening for the light in your trailer to install it. The mounting flange is metal. There is also a Stainless Steel Trim Ring # A5TRSSB available. It does not include a gasket, however If you would prefer...

  • Can Sealed, 4" Round LED # STL42RB be Ran as Extra Stop/Turn Signal Light
    The Sealed, 4" Round LED Trailer Stop, Turn and Tail Light, Flange Mount, 3-Function, 10 SuperDiode # STL42RB can be ran to the rear of a vehicle as additional stop/turn lights. Basically you'd just need the correct install harness like the # A47PB which you'd wire to the vehicle wiring and you'd be set.

  • Replacement LED Tail Light For Pacific Trailer
    We have LED trailer lights available. If you have the dimensions of the light you want to replace that would help in finding the right replacement for your Pacific trailer. From my research I found that some of the Pacific trailers use part # STL42RB. This is a 4-inch round flange mount light that has 10 LEDs. It is a three function stop/turn/tail light. If you need a flush-mount light, we also have part # STL43RB. this is also a 3-function 10-LED light. If you are looking for an oval...

  • Converter Recommendation to Install Combined Taillights on a Flatbed Truck that had Separate Bulbs
    It sounds like you need to convert the separate wiring of your 1991 Nissan truck to a combined setup to work with the Round LED Taillight # STL42RB. For this you will need to get a Roadmaster Brite-Lite Wiring Converter # RM-732. You will run the wires from your vehicle to the right side of the # RM-732 by function, and then from the left side of the box you will run the corresponding left or right turn signal wire to the red wire of the # STL42RB. The tail light circuit will bypass this...

  • Replacement Optronics 5-1/2 Inch Diameter Round LED Trailer Light
    I think the part number you have on your trailer is part # STL42RB. The other numbers may be a serial number or another number for a mold or something else. The best way to see if our light is the exact replacement is to check the specs and the mounting of the # STL42RB. The light has 10 LEDs and uses a 3-prong plug like part # A47PB for the right angle plug or part # A45PB for the straight plug. The dimensions of this light are 5-1/2 inch diameter and 1-15/16 inches deep. The mounting...

  • Troubleshooting Running Lights Circuit on a Travel Trailer Tail Light Harness
    Since you have tested the 4-Way connector on your vehicle and it is working properly, it leads me to believe that the wiring of the lights is incorrect. You will want to make sure that the fuse for the running lights on the vehicle is not blown. It sounds to me like the lights you have only have two wires coming out of the back for wiring to the trailer connectors wiring. If this is the case then the red wire will connect to the yellow (left) and green (right) wires on the trailer lights....

  • Replacement Option For Glo-Brite 9891-88 LED Trailer Tail Light
    We do have an option for you to replace your Glo-Brite 9891-88 LED trailer tail light. Based on my research this is a 4 inch round LED tail light that uses a 3-wire plug and fits in a 5-1/2 inch grommet. We have exactly that with the following light: - Optronics LED Trailer Tail Light # STL42RB This comes with the grommet, which has mounting holes separated on center by 4-1/4 inches, so the only other thing you will need is the 3-wire pigtail, and you can choose from a standard or right...

    I'd be happy to assist you. It sounds like you need the Sealed, Flush Mount Tall Rectangle LED Trailer Stop, Turn and Tail Light, Grommet and Plug, 12 Diode # STL34RB but most of the pictures I see have round tail lights like the Sealed, 4" Round, LED Stop/Turn/Tail light, 21 Diode - Red # STL55RB.

  • Correct Wiring Needed to Install Optronics Round LED Trailer Light
    To install the Optronics Round LED Light # STL42RB you can use the Optronics 3-Wire Pigtail # A45PB. This has the three 20 gauge wires for stop, turn, and tail light functions. The red wire is for stop and turn, the black for tail lights, and the white is the ground wire.

  • Replacement Tail Light for 2009 Ranger Boat Trailer
    Sometimes it is possible to replace a broken trailer light with one that uses a different type of installation but since we offer a very wide range of lights you may very well be able to find an exact OEM-style replacement. It sounds like you have a light like # STL42RB which has a 3-hole mounting flange. I linked our main page for trailer tail lights of all shapes and sizes. On the page you can simply click on the filters for light shape, light type (LED or standard bulb), lens color,...

  • How to Connect the # STL42RB Tail Lights to a 1958 Trailer with 2 Wire Lighting System
    The 4 inch Round Sealed LED Stop, Turn or Tail Light, item # STL42RB, uses a 3 wire pig tail, item # A47PB or # A45PB, to connect to your existing trailer wiring. The plug on the pigtail plugs into the back of the tail light and is then hard wired to your trailer wiring. It sounds as if your original tail lights were grounded to the trailer frame through their mounting studs, so a third wire was not needed. When connecting the 3 wires from the 3 wire pig tail, you will ground the white...

  • What is Needed to Replace Incandescent Lights on Trailer to LED Assemblies
    You can absolutely replace the incandescent lights on your livestock trailer with LED assemblies. Other than replacing the lights themselves, there is nothing else that you will need to do. Your existing wiring (assuming it is in good condition) can be left untouched. You will find that the new LED replacements will provide a brighter light on your trailer and also won't require near the power demand that your current incandescents need. I have attached a link that will take you directly...

    The Buyers Products Tail Light Mounting Box - 4" Round Hole # 337LB663 is designed to be used with something like the Rubber Grommet for 4" Round Trailer Lights # A45GB and Optronics LED Trailer Tail Light - Stop, Tail, Turn - Submersible # STL55RB. The light will snap into the grommet, which will then snap into the mounting box.

  • Recessed Round LED Red Trailer Lights That Can Function as Brake Lights
    The Piranha LED Trailer Clearance and Side Marker Light # PE46NR should only be used as a clearance or marker light. It does not have the brake light function built into the light like the Optronics LED Trailer Tail Light # STL42RB. The Optronics light will require a 3-Wire Pigtail # A45PB to be wired into your trailer wiring.

  • What is the Power Draw of Optronics LED 4 Inch Round Trailer Tail Light # STL42RB
    Because tail light # STL42RB has more than one function it has more than one amperage draw rating. Brake lights and turn signals draw more power so that will be the higher draw at 0.413 amps. Running lights use less power and would be the 0.26 amps. If you have the running lights on and then step on the brake, the brake light overrides the tail light. If you have the brakes on (with or without the running lights on) the turn signal will override the brake light on that side. So the most...

  • Does Sealed, 4" Round LED Trailer Tail Light STL42RB Also have Reflectors
    Trailer tail light # STL42RB has reflective properties but I recommend # STL43RBX. The mounting ring around this light is a reflective lens rather than just a black ring like with # STL42RB. I also recommend wiring harness # A47PB to plug into the back of the light.

  • Replacement Lights for 1989 Interstate Box Trailer
    The diameter you are looking for is 4-1/2" on the # STL42RB. This would be the widest part that would fit into the hole on your trailer. We do not have an LED option without the plug but we do have the Peterson # PM425-3. This has the same mounting hole dimensions and is also 4-1/2" at the widest point on the back. If you decide to stick with the Optronics light you will need the # A47PB or # A45PB.

    I am not entirely sure what you are asking but the Optronics LED Trailer Tail Light part # STL42RB is a flush mount trailer light that is designed to be installed on a flat piece of metal in a 4-1/2" diameter round hole with a self tapping screw like the Self-Tapping Phillips Head part # 1131832.
