Optronics ST57 Series Combination Tail Light Dimensions

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 circuit board is sealed, which means that water will not damage the diodes or circuit board.


Combination Lights for Trailers Over 80" Wide

Flatbed trailer over 80" wide with combination tail lights

If a trailer is 80" or wider at its widest point, then it requires rear clearance lights in addition to basic trailer lights. These clearance lights indicate the width of the trailer when it is viewed from the back.


To meet these requirements on a flatbed utility trailer where the bed extends past the wheels, you can install combination trailer lights that include the rear clearance function. For proper mounting, the lights must be installed at the widest points on the rear of the trailer - one on each corner.

Video Transcript for Optronics Trailer Lights - Tail Lights - ST57RS Review

Speaker: Today we're going to be taking a look at Part Number ST57RS. This is the Optronics part number ST57RS. This is the Optronics Tall Rectangular Submersible Trailer Tail Light and License Plate Light for the left hand side of your trailers. This is designed for trailers over 80 inches wide. The red, rectangular trailer light is going to serve eight functions for trailers more than 80 inches wide, such as your stop, turn, tail, rear-clearance, rearreflex, side marker, side reflex, and license plate illuminator and you can get that license plate light here on the bottom. The inside's going to contain three bulbs; you're going to have your main bulb, you're going to have a separate bulb for your side marker or clearance light, and then you're going to have a bulb for the license plate light as well. This is waterproof and corrosion-resistant.

It's going to feature a replaceable snap-on lens with three incandescent bulbs. The shock-proof sockets are going to guarantee long bulb life. This is a universal mounting design. Here at the back it's going to feature two mounting slots, mounting hardware is included. These slots are going to be separated center-on-center by right around two inches.

The wiring design is going to contain three wires, so you're going to have your white wire for your ground, the brown wire's going to be for the taillight function, and the yellow light is going to be for your stop and turn single. Again, it's going to power the rear clearance, the license plate light, everything that you need, side marker. To go over the overall measurements real quick, I'm going to measure here at the base or the backside of the light. It's going to give us a length of about 6 and 1/16th of an inch, and overall width of 3 and 3 quarters and then the depth is going to measure about 2 and one quarter of an inch. This unit is Department of Transportation Compliant. I'm going to go ahead and hook it up to our external power source that way you can see what it looks like with power running to it, and we'll also be able to turn off our overhead lights that way you can see it and a low-light setting.

This is going to be the taillight function right here. Since I have a nice, consistent signal, you've got the light here on the bottom that's going to allow somebody 00:02:07 that's come down for your license plate and then we apply our breaks, you can see how it illuminates, it sends out a stronger signal, you get that side marker light as well, and it's going to function as our turn signal. That's going to do it for our review of Part Number ST57RS. This is the Optronics Tall Rectangular Submersible Trailer Tail Light and License Plate Light for the left hand side of your trailers. .

Trailer light problems are the bane of anyone (like me) who has a number of toys, all of them on trailers. This time fixing the lights on my Shorelander PWC trailer was fast and trouble free. I replaced the rear drivers side assembly (backed into something) with this item from etrailer. The price was very good, fast shipping and the light fit with no modifications necessary. Oh, and it worked ! Thank you etrailer for a trouble free trailer light fixing experience. 411940

Ask the Experts about this Optronics Trailer Lights

  • Replacement License Plate Holder and Light for Shorelander Trailer
    Often the license plate holder has an integrated light that requires replacing the entire holder as well. I recommend the LED Trailer License-Plate Light w/ Mounting Bracket - 2 Wire - 5 Diodes - Clear # LPL56CB because there are no bulbs to replace and there is a lifetime warranty on the LEDs. You will need to cut the wires and reconnect the new ones. If you have something more detailed, send me a photo and we can continue to troubleshoot.

  • Replacement Submersible Tail Lights for a Shorelander Boat Trailer
    First, the additional function is a license plate light. If your license plate is mounted and/or illuminated elsewhere then you could use 2 right side lights. When replacing trailer lights it is best to go with all LEDs or all incandescents. Mixing the types can result in lights not working or overdraw on the LEDs. Otherwise you can use either one. The dimensions, 6-1/16 inches long x 3-5/8 inches wide x 2-1/4 inches deep, for # STL56RB are correct. Rear reflex means that the lens...

  • Trailer Right Turn Signal Does Not Work and Left Signal Comes On Instead of Right
    The first thing you are going to want to do is isolate the issue. Disconnect the trailer from the vehicle and use a circuit tester, # 40376 if needed, to test the wiring on the vehicle. If you are using an aftermarket converter on the vehicle first test the wires leading into the converter box. If the signals are not correct then there is an issue with the vehicle wiring you will need to track down. If the signals are correct going in but not coming out at the connector then that indicates...

  • Left Hand Side Trailer Light to Match ST56RS
    The left hand version of the part # ST56RS is actually part number # ST57RS. The biggest difference is that this one has a light for the license plate that would be mounted below it. Aside from that it's no different. Only other difference is it has a yellow wire instead of a green wire for the stop/turn signal.

  • Removing Existing Trailer Taillight
    The procedure from removing your existing lamps will depend on the lamp itself. If your current lamp is part # ST57RS, there are bolts on the rear of the lamp that pass through the mounting bracket on the trailer. Once these bolts are loosened, the lamp will pull away from the trailer frame. If you have a different lamp, send me a photo by replying to this email.

  • Replacement Wesbar Taillight For Shorelander Trailer
    I did a Google search on the 5110310 part number you provided, and couldn't find any reference to it. Perhaps this was Shorelander's internal part number for the lamp? If you click the provided link, you can see the Wesbar taillights we offer. I do know that the # 403025 was commonly used by Shorelander. Given the measurements you provided, # 403025 is the likely replacement. If you'd care to reply with a photo of the remaining passenger side lamp, I'd be happy to look into it further...

  • Recommendations for Waterproof Tail Lights for a Boat Trailer
    Optronics tail lights # ST56RS and # ST57RS are submersible assemblies. This means that water can drain out of them. What I recommend are sealed lights such as # STL57RB and # STL56RB so water cannot get in at all. Sealed lights will have far less issues than regular submersible lights.

  • Recommended Replacement Tail Light for Boat Trailer
    The Optronics ONE Series Marine LED # STL0016RB you asked about is 8 x 2-7/8 by 2-13/16 inches. I've attached a diagram to assist. The closest tail lights to your 3-3/8x5-7/8 measurements on your boat trailer are the STL57RB for the driver's side and STL56RB for the passenger side. These LED submersible lights are 6-1/16 x 3-5/8 so just slightly larger. For incandescent lights, I recommend the Optronics 6-Function Tail Light - Submersible - Passenger Side # ST56RS and driver's side...
