Great, simple tail lights. An exact replacement for what they used in 1970 when they homebuilt the trailer. I wanted something that would fit in the tubes to protect them from the heat of the firebox and damage. A perfect set to make the BBQ Pit road legal again.

Wish i would have paid the extra and gotten the Metal Housing Tail Light. What i have is working well and should last.

Very easy to install, looks awsome on my trailer

We purchased an old snowmobile trailer to adapt to a hauling trailer. The lights were long gone but the steel surrounds were still there. We were able to order the exact light fixtures that had been in the surrounds even with the right mounting bolts on the back.. Made for a quick clean installation.

Great people, had problem with my order, e-mail them, and they fixed it just a little long on shipping would buy from them again

For the price and function you can't beat it, I used them on the back of CJ5 and they get shaken pretty good---work great

Inexpensive, fit my old trailer exactly. One of the bulbs burnt out shortly after I began using, but other than that very good.

Trailer lights are working fine, thanks for asking!



- ST24RB
by:

For the money, these work fine. Don't expect very a very durable product though. They are cheaply made, and looks like water can get in eventually. Fine for a rarely used trailer.

These were hard to find but etrailer had just what I needed with incredible shipping and customer service.

Just what I needed for an old boat trailer I am restoring look just like the original ones and work great"

Just what I was looking for. Came to me very quickly and was kept informed of tracking. Also asked a question of their experts and was answered very promptly.

This is a good, inexpensive light. I'm not ready to move up to the LED type yet. I only need 4 lights but why not have a couple of spares sitting on the shelf? Thanks again, Mad Max

Ask the Experts about this Optronics Trailer Lights



  • How Does the Replacement Lens for Optronics Install
    Yes, the Replacement Lens for Optronics # A24RB which is designed as a replacement for the Trailer Tail Light # ST24RB and # ST25RB does snap onto the tail light assembly.

  • How Does the Optronics 3-Function Tail Light Provide 3 Functions if There are Only 2 Wires
    The Round Trailer Tail Light # ST24RB grounds through the mounting studs so the two wires are all that is necessary for activating the stop/tail/turn signals of the light. The bulbs are dual intensity so each wire will control a different intensity of the bulb and then ground through the mounting studs. The stop/turn will be on one wire and the tail light will be on another. To determine if you need more lights at the rear of your vehicle you will need to consult your local laws and regulations....

  • Availability of Surface Mount 4" Round Trailer Taillight That Uses 2 Studs On Back To Mount
    I have another option for you, but we do not have an LED light that mounts in the same fashion as the Trailer Tail Light - Stop, Turn, Tail - Incandescent - Round - Red Lens # ST24RB so you would not be able to install an LED light in the mount you have on your trailer. The only option would be to stick with an incandescent light like the # ST24RB. Since they are mounted inside of the can you can use two # ST24RB as you do not need the license plate light. I included a video of the #...

  • How Do I Ground The ST24RB Tail LIght To My Trailer
    The Trailer Tail Light - Stop, Turn, Tail - Incandescent - Round - Red Lens - Passenger Side, part # ST24RB, has studs that will screw into the frame of your trailer. Those studs will act as the ground for these lights. If the lights will not mount directly to the metal frame of your trailer, you will have to add a jumper wire to ground the lights. I have included a video demo link below.

  • Does 7 Inch Round Transit Light, # ST90RB, Have Brake, Turn, and Tail Light Functions
    The 7 Inch Round Transit Light, # ST90RB, is a 2-function light. This round red transit light is used as a stop and tail light when connected to combined stop/turn circuit. For stop, tail, and turn lights, you will need a 3-function light like # ST24RB.

  • How Many Functions Can the 7 inch Round Transit Stop and Tail Light # ST90RB Do
    This 7 inch Round Transit Stop and Tail Light # ST90RB can do stop and turn signals when used on a combined stop/turn circuit, but it cannot do taillight functions as well. The closest thing to a 7 inch 3 function trailer light we have is the 4-3/8 inch Round Trailer Tail Light, Stud Mount, 3-Function Trailer Light # ST24RB. However, this light is only 4-3/8 inches in diameter.

  • What are the Wire Functions on an Optronics 3-Wire Pigtail
    On the Optronics 3-wire plugs the white is ground, red is turn signal/brake lights, and the black is for running lights. On your trailer green is likely the right turn signal/brake light wire, brown and tan are most likely running lights, and yellow is most likely left turn signal/brake lights. You will need to use a circuit tester such as # 40376 to test the wires on the trailer to confirm.

  • 4 Inch Round Submersible Trailer Light Recommendation
    I have a solution for you, but the 4-3/8" Round Trailer Tail Light # ST24RB that you referenced is not submersible. The closest thing we have to what you referenced that is submersible would be the Red Flush Mounted Sealed Turn Signal # 435800.

  • Replacement Trailer Tail Lights for River Drift Boat Trailer
    The Peterson Round Trailer Tail Light, 2 Stud Mounting, Right Hand # 431800 and # 432000 or the 4-3/8" Round Trailer Tail Light, Stud Mount, 3-Function, Right Hand # ST24RB and # ST25RB are both the style you are seeking but are not submersible. They are good for weather, but not for launching a boat as you referenced. I have linked the page to your options for a round light that is submersible but they won't have the 2 stud mount your referenced.

  • Sealed LED Tail Lights on Trailer Do Not Illuminate But Incandescent Type Will Work
    The Optronics Submersible LED Trailer Light Kit, part # TLL9RK, provides a lifetime warranty on the the LEDs and features water-proof housings. This particular product uses two threaded stainless steel studs for mounting to your trailer and a 3-wire configuration for electrical connection to your trailer wiring. The light includes separate wires for ground (white wire), stop/turn signals (green and yellow wires) and running lights (carried on the brown wire). There are similar products...

  • Why is There a Driver and Passenger Round Optronics Trailer Tail/Stop/Turn Light
    The Trailer Tail Light # ST24RB is labeled as the passenger side because the driver side option, part # ST25RB, has a clear section on the underside of the housing to illuminate a license plate on a bracket like part # LP10SB. If you already have a light dedicated to the license plate then you can definitely use 2 of the passenger side options for your trailer. Attached are some review videos for you to check out. These light assemblies ground through the mounting hardware and then you...
