I wanted to change out the rear lights on my 1949 Chevy 3600.

This is a daily driver for me, not some show truck, so I wanted to protect the lights as well.

I started with a piece of 6” schedule 40 pipe. Then I cut a disk to mount the lights on with a hole saw and welded them in place.

I cut a slot into the bottom of the driver’s side light and milled a matching slot in the pipe. This was to allow light to shine down on the license plate.

Then a drilled and tapped #6-32 holes in the edge of the pipe so that I was able to screw the protective expanded mesh onto it.

Last, I primed and painted them up to match as close a possible.

Very happy with how it all turned out.

GREAT- Everybody love them.



by:

this was a very easy install. the holes were already there to place the lights. I ran new wiring from the hitch all the way to the lights. I brought the wiring in near the circuit box up front and ran it in the cupboards to the rear. (it was easier to run new wires, the old ones were pieced together) I also was able to get the dents out and stablize the bottom of the wall. I would recomend redoing the wires when you do this. It saves a lot of headaches trying to figure where your wire may be bad. The old lights were big and boxy.

I often recommend Etrailer to people in my community of RV repair and Renewable Energy. I wish someone would do a video on how to replace hubs-wheels-bearings on older travel trailers with the Dayton-Dexter-Fayette Star wheels and include details on how to identify the axle and weight class. If you want to see what your products have been used on, heres an Example. I bet you never thought Etrailer would be the source for parts on a wind turbines pivot, shaft and furling parts!

Very nice light. It flush mounts and is a easy install. I needed something of this type for my bantam trailer rebuild and these worked great

After a year of being submerged in creek crossings, surviving being beat on washboard and washed out roads the lights are still working great and bright as ever.

Thank you very much perfect fit just like it was made for it. Do you know how can find out more about this trailer?

It looks like an old livestock or horse trailer. The stamp on the back that says longhorn trailer company in Wichita falls, Texas closed in 2014. They were open for 68 years so its hard to tell how old it is.



by:

The Right Light at a GREAT PRICE! Easy to install and exactlly what was needed for my 1952 Stewart Coach. So glad I found your site and will continue buying all of my trailer needs with etrailer.com.

Perfect fit ???? you guys are the best

Work great, easy to install.....4.5 inch hole saw does the trick.

Light was inexpensive but still well made. Easy to install - replaced the rusted out tail lights on my cattle trailer

GREAT LIGHTS!

Easy to install. Works well. Just like the original. I would buy again, if I need to.

Just perfect.

I purchased the Optronics Trailer Tail Light - Stop, Turn, Tail - Incandescent - Round - Red Lens for my camper. They were an exact match to the originals! Easy to order, great price, received quickly, easy to install, quality construction, just what I needed. Super service, I couldn't be more pleased or impressed with your company. A true pleasure doing business with you!



by:

I purchased these to provide a look that I wanted on my 1954 1/2 ton flatbed.
I have only put 12 volts to them for test purposey to this point in time. I have been working on this project since 1999. It is now in it's final stages of construction as the body parts are now being painted. The, the lights, were placed in a 2x6 inch tube, on the end, to look like stop and turn lights on vehicles of that period in time, in the bumper. I went for the bulb look, not the l.e.d. for the look. Very happy with my choice.



by:

Installed the trailer lights and found problem with the outboard right light. The trailer has one light on the fender and two lights embedded in the tail cross piece. The problem was that when the running lights were on the outboard light was on the high side of the bulb and when grounded came on as a stop light. I spent several hours tracing wiring and got nowhere until I substituted an old square light and found that the problem went away. It seems that the pigtail that is in the bulb socket was installed with the low side in the high side hole and the notch matched up with the correct axis making the problem confusing and hard to detect. Although the bulb orientation was correct power application was not. Removed the wires and re-inserted them in the correct position and problem was rectified. Quality control problem? Otherwise great product at a great price



by:

Fit perfectly, nice look, great quality. Thank you

Product Review:I had these type lights on an old Toyota rust-bucket with a wooden bed which still is my most loveable vehicle; can't find these lights locally (N/W NC mountains); found your ad online and hoped these would match those already on the Toy and replace some damaged and rusty; couldn't believe I could get exact replacements, but I sure did; order date March 29 early AM, mailman handed them to me April 31 at 1 PM at my house "in the same year!" They had traveled, according to map, across from the edge of Missouri through the southern edge of Indiana, across the length E-W of Kentucky, SW Virginia to Greensboro, NC, then backtracked on land back to my home via USPS to me. Put them to your ear and you could still hear the Mississippi!!

Give it a big 5 stars!



by:

I have been building trailers and truck beds for a while. I really like using the flange mount vs the rubber gasket and you can replace the bulb instead of a new light assembly.



by:

Every item works fine! Parts were delivered in a timely fashion. Installation went well on a 25 yr old trailer. Thanks for being a source for repair parts on this older equipment!



by:

Tail lights work great. Everything was included that needed to be. Used them on two old trailers, making them more visible and legal. Fast service. Great price.



by:

Perfect replacement for the tail lights on my old trash trailer. Mounted the lights and new wiring in an hour.



by:

Simple, classic, GREAT replacement for old cracked lens on 1969 Nomad. Will post a pic when I install. Super simple wires should make this a very easy install. I like the recessed lens as well as the snap ring which holds it back in the black metal case. Makes for great protection of lens and easy bulb replacement in the future.



by:

The groove for the retaining ring is virtually nonexistent. Tap or jiggle it a little bit and the ring pops out and then the lens. I had to apply a couple dots of clear caulk around the lense and ring to keep them in place. But it works for a $5 taillight.

  • 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...

  • 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....

  • Comparing Optronics # ST40RB and Optronics # STL003RFLB Trailer Lights
    Aside from the Optronics # ST40RB having an incandescent bulb and the Optronics # STL003RFLB being LED the only other big difference is that the first part grounds through the mounting hardware while the LED version grounds through a wire. This is why one unit has 2 wires and the other has 3. We have 2 pigtail options for the LED verison for you to use. Part # A45PB has the wires coming straight out of the plug while part # A47PB has a right angle for tight spacing where your lights mount. I...

  • Magnetic Flat Towing Tow Bar Wiring Kit Flashes Both Turn Signals Instead of Just One
    On a 7-Way, just as a 4-Way, the turn signals and brake lights are combined on the same circuit on each side. So yellow is left turn and brake, green is right turn and brake, brown is running lights, and white is ground. Usually when there is a red wire it is brake lights. But on a combined system like this the brake lights should be combined with the turn signals. There could be a short that is causing both turn signals to activate at the same time. You will want to inspect the wiring...

    The Replacement Tail Light Lens # A40RB is not held on with screws.

    The closest to 4 inch round lights we have is the Optronics LED Trailer Utility Light # BUL43CB or Trailer tail Light # STL55RB which are actually 4-5/16" diameter x 1-15/16" thick. These are designed to fit the Rubber Grommet for 4" Round Trailer Lights - PVC # A45GB which requires a 4-1/2 inch diameter cutout. You will also need wiring pigtail # A47PB.

  • Recommended Round Trailer Tail Light With Bright White And Red Light Functions
    Hey Rob, The best option for both a red and clear lens that's going to produce a bright light is going to be the Fusion LED Hardwired Trailer Light # OPT97NR. It's the same 5-1/2" overall diameter as the # OPT89NR (BUL11CRMB) but it does have to be hardwired instead of using a plug-in connector. You can just cut of the old connector from your trailer's wiring and splice the new light in with some heat shrink butt connectors # DW05744-10.

  • What are the Wire Functions on Trailer Tail Light # ST40RB
    Trailers have tail lights that have a combined brake and turn signal on the same circuit. For light # ST40RB as an example, the green wire carries right turn and brake lights. The brown wire is only running lights. It sounds like you attached the brown and yellow wires on the tail light to the brake and turn signal wire from the trailer connector. The trailer connector at the front of the trailer should have 4 wires coming out of the back of it. The covered pin is the ground wire. The...

  • Troubleshooting No Trailer Running Lights
    I would begin by testing the trailer connector on the vehicle to rule that out. Turn the headlights on and use a circuit tester like part # PTW2993 to test the socket on the connector fed by the brown wire. If you are not getting a signal on this pin, you might have a blown fuse. Make sure the ground wire from the connector on the trailer is securely grounded to the trailer frame and that each lamp is grounded to the trailer frame either by an individual ground wire connected to the trailer...

  • How to Remove Tail Light That Has Rivets Holding the Grommet in Place
    It all depends on how the light installs. If it is like the Optronics part # ST45RB that installs with the grommet # A45GB then you should be able to remove it without removing the grommet. You may need access behind the light to do this though. If your tail light is more like the Optronics part # ST40RB though where the grommet is part of the light then you will need to remove the rivets by drilling them out and then use new rivets or even screws to install the new tail light (or the...

  • Trailer Clearance Lights Show Power but Some Will Not Light Up
    It is possible that the clearance lights are not working if you have a lot of clearance lights. This can overload the trailer wiring on the vehicle side and cause some of the lights not to work. You can check the amperage draw per clearance light by testing one at a time using a multimeter such as # PT89ZR. Switching everything over to LEDs will be much better because they draw only a fraction of the power compared to incandescents. Another possibility is a poor ground connection. All...

  • Troubleshooting the Brake Light Function of the Optronics Round Trailer Light part # ST40RB
    The Round Trailer Stop, Turn and Tail Light # ST40RB that you referenced grounds through the mounting hardware.

I would make sure that this light is installed on a clean metal surface that touches the frame of your trailer. If not, you could run a jumper wire from the mounting hardware of the light to the frame of your trailer to improve the light's grounding. You could also test the assembly...

    There are a couple of things that you can check to see what the problem is with your trailer light. Since you mentioned that power is getting to the light it could be that the circuit is not being completed meaning a bad or weak ground connection. Light # ST40RB grounds through its mounting hardware. The attachment point must be clean and corrosion free. If there is anything between a light ground and the metal trailer frame or if the trailer has an aluminum frame, tilt bed, or folding...

  • With Trailer Connected Truck Reverse Lights and Trailer Brake Lights Are Not Working
    It sounds like you might have a few different issues going on here. First, we need to test the vehicle side 7-Way connector to make sure it is working properly. Use a circuit tester such as # PTW2991 to test the pins on the connector while someone sits in the truck and runs through the light functions. If something does not work then you will need to determine the problem. Check the trailer connector for corrosion inside and out. Corrosion can cause all sorts of issues, so can ground...

  • What is the Difference Between a Snap Ring and Retainer Ring for a Trailer Tail Light
    There really isn't a difference. Snap-ring and retaining ring such as # 410-21 are two names for the same thing. If your tail light looks like # ST40RB then use # A40SRB. But you mentioned that the light was 4 inches, which is what Peterson light # 429800 is. So for that light use # 410-21. Shipping can vary depending on the option you choose and where you live. So take a look at the link to the right that explains more about shipping and how to determine cost.

  • How to Determine the Functions of the Trailer Wiring on a Triton Trailer
    Most likely the white is ground, the brown is tail lights, the green is right turn/brake and the red is left turn/brake, but since the colors are a little different than the standard I would recommend you wire the trailer by function instead of color. This way you will eliminate and guess work and you will know that your trailer is wired correctly. The easiest way to do this would be to get a car battery and use a jumper cable to put current on each wire to see what tail light functions...
