Features to know about
Reliable Lighting in Harsh Conditions: Fully Sealed and Submersible Design
If your trailer ever sees water, this light is ready for it. The circuit board and housing are completely sealed, keeping the 23 diodes and internal electronics dry even when submerged. It’s built for reliability in wet environments, so you don’t have to worry about corrosion or shorts after a dunk at the ramp or a drive on rainy roads.
All-in-One Functionality: 8 Lighting Features in One Compact Unit
This low-profile light packs eight functions into a single housing—stop, tail, turn, side marker, side reflex reflector, rear clearance, rear reflex reflector, and license plate light. At 7-7/8" long and 3-1/4" tall, it covers all rear lighting needs for trailers over 80" wide without adding bulk or needing extra fixtures. One light does it all, keeping things clean and simple.
Efficient LED Performance: Bright Output with Minimal Draw
Forget about changing bulbs or dealing with burned-out filaments. The 23 long-lasting LEDs provide crisp illumination while pulling very little power—just 0.181 amps for stop/turn and 0.047 amps for side marker at 12.8 volts. That means brighter lighting with less strain on your trailer’s electrical system and far less maintenance over time.
Wide Visibility Coverage: PC-Rated for 180 Degrees of Light
Safety is about being seen from every angle, and this PC-rated light shines a full 90 degrees in either direction from centerline for a total of 180 degrees of visibility. Properly mounted, it covers both rear clearance and side marker functions, improving visibility in traffic and at night from multiple viewing points.
Straightforward Mounting and Wiring: Surface Mount with Molded Plug
Installation stays easy with the surface-mount setup and included hardware. The molded 2-way plug and separate ground wire simplify the wiring process—whether you keep the quick-connect or cut it to use standard butt connectors. Either way, it’s a tidy install that keeps connections protected and secure.

Very quick turnaround. Thanks so much.
But had to cut off the two pronged connection to splice into the boat trailer’s three prong wiring harness.

Opened up the package, Walked out to my boat, snapped off the old light, snapped on the new light, fired up the truck and poof there were lights. Bought two one for the next time.
Trailer maintenance is no longer a big deal.

Well about a year has passed and the lights are still perfect. No issues what so ever. Since then I have added reverse spot lights, led strips, and replaced the marker lights. Etrailer is my go to.

Javelin Boat trailer tail lights. Original lights were pre-wired with 2 prong plug. Needed to replace lights. Wanted same lights.
Dealer did not stock, was not helpful in finding them.
etrailer was amazing. The young lady whom I dealt with was extremely helpful. Found the correct lights for me. Installation was a breeze. Lights work beautifully.
Definitely 5 stars. Will use again.

The light was easy to install on my trailer both because the light housing is easy to work with and mount and also because the wiring plugs matched the existing wiring plugs on the trailer. The older incandescent lights had failed due to water getting into the housing. These lights seem to have a nice solid seal and also the LEDs should be resistant to failure if a little water leaks in over time. Also the LEDs are much brighter than the older incandescent lights we replaced. Very pleased with this product.

Order these boat lights for a friend of ours boat trailer, they arrived sooner than we expected was so easy to install and works great, looks awesome, very pleased.
I called first to see if they carried these taillight and the employee was so nice and helpful, she offered to send a e-mail with the link to order the tail lights, very polite and concerned about our purchase.
We would definitely recommend this company and very impressive with the employees that helped make sure we got the right items we needed.
If I could give them l0 stars I would. Thank You.....

These lights are great. The original lights were just bulbs and the seals would fail, allowing water to get in. These LED lights are bright and waterproof and were a perfect replacement.

See what our Experts say about this Optronics Trailer Lights
- Passenger Side Light That Matches The Driver Side Optronics LED Tail Light STL37RPGHi Robert! Though we have another option that is extremely similar, the passenger side that matches the Optronics LED Tail Light for Trailers Over 80" Wide - 8 Function - Submersible - 23 Diodes - Driver Side # STL37RPG (part # STL36RPG) was discontinued about a year ago, unfortunately. With that said, the following parts are nearly identical: Optronics LED Tail Light for Trailers Over 80" Wide - 8 Function - Submersible - 23 Diodes - Driver Side # STL37RB Optronics LED Tail Light for...
view full answer... - Replacement Lights for Lumiere LED Lights 278002564 and 278002565Hey Matt thanks for the information! We do not have those exact lights available as they are OEM, but I do have a comparable option with the same connector. They are the LED Tail Light for Trailers - Passenger item # STL36RPG and Driver's Side item # STL37RPG. These are 7 function LED lights that have stop light, tail light, turn signal light, side marker light, side reflex reflector, rear clearance light, and rear reflex reflector. I have attached a diagram below that will show you the...
view full answer... - Replacement Options for Wesbar 271594 With Broken LensThe Wesbar 271594 is a sealed light which means the lens is not replaceable. The only solution is to replace the entire light. The parent company for Wesbar recently changed, so as of May 2023 this particular light is on indefinite backorder. I recommend replacing both of your lights with a similar light like the Optronics # STL36RPG and # STL37RPG. These lights have a wraparound style like the Wesbar and similar dimensions at 7-7/8" long x 3-1/4" tall x 2-7/8" deep. They also use the...
view full answer... - Replacement Tail Light For Wesbar Wrap Around Trailer Tail LightI recommend replacing your Tail Lights with the Drivers # STL37RPG and Passengers # STL36RPG lights as the Wesbar Lights and lenses are obsolete. The Optronics lights above will both use the same Tail Light Lens # A39RB if either side were to become damaged. So you will only need to keep one spare on hand versus having both sides and only damaging one side.
view full answer... - LED Replacement Lights for a Boat Trailer with Wesbar 105826 Tail LightsFor an LED replacement that is nearly identical to the Wesbar 105826 light you can use # STL36RB for the right side and # STL37RB for the left side. There are also versions that have a plug instead of just bare wires. For the right side use # STL36RPG and for the left use # STL37RPG. I have linked a couple of review videos for you as well.
view full answer... - Trailer Tail Lights With 2-Prong Connector For ShoreLand'r Boat TrailerCurrently the only way we have tail lights with the quick connector like you have is the Drivers # STL37RPG and Passenger # STL36RPG tail lights. These lights are submersible so they are compatible with your ShoreLand'r boat trailer.
view full answer... - Replacement Light for ST-36-RH Tail LightTo replace your trailer's ST-36 RH light, you will want the Optronics Aero Pro Trailer Tail Light item # STL36RB. This will be a direct replacement for your passenger side light. The driver's side replacement is item # STL37RPG.
view full answer... - Replacement Taillights for 2001 Procraft Boat TrailerThe Trailer Light Kit # TL16RK is a great option for your trailer as it comes with new wiring, taillights and clearance lights. However if you don't need the wiring, license plate bracket, and clearance light it might be better just to go with individual lights like part # STL37RPG and # STL36RPG. That being said the LED Over 80 kit would be the part # TL16RK. The clearance lights and the taillights do not share the same circuit so them being of different light styles would not be an issue.
view full answer... - LED Tail Lights with a Plug-In Connector for a 2008 Bass Tracker- Trailstar Boat TrailerWe do have the lights you are looking for. For the right hand side use Aero Pro Submersible LED Trailer Tail Light # STL36RPG. It is the same light only with a 2-wire molded plug. The matching left hand side is # STL37RPG.
view full answer... - Matching Connector for the Optronics Trailer Taillights # STL36RPG and # STL37RPGFor the Optronics trailer taillights # STL36RPG and driver side # STL37RPG we do carry the style of connector it uses with the part # 9651P. You'd cut the harness in half and wire either side to your trailer wiring so that you can easily connect to the lights mentioned.
view full answer... - Replacement for Wesbar 271575 Trailer Tail LightHi John, great question The Wesbar 271575 tail light is no longer available, so we do not have it in stock. The good news is that there are replacement options. I recommend the Optronics LED Driver Side Tail Light part # STL37RPG along with the matching Passenger Side part # STL36RB if you need a pair. These lights provide the same major lighting functions including stop, tail, turn, side marker, clearance, reflector, and license plate illumination. They also have the same mounting dimensions,...
view full answer... - Wiring Compatible with the LED Tail Lights with SAE 2 Wire ConnectorThe SAE two wire connect is sometimes a factory connection, but you can simply cut the connector and use butt connectors like # DW05744-5 for the LED Tail Light for Trailers Over 80" Wide - 7 Function - Submersible - 17 Diodes - Passenger # STL36RPG and driver side # STL37RPG if desired. If you want the quick connect, then I recommend getting the 2 Wire Loop, 12" # 9651P and cutting the middle to give you the two quick connectors you need for that lighting kit to have the quick connects...
view full answer... - Can I Use New LED Trailer Light With Molded Plug On Trailer Without PlugIt looks like the new light that was purchased part # STL37RPG has a molded 2-way plug and separate ground wire and your trailer wiring has loose wires. You can cut the plug off and attach the appropriate wires to your old wiring by function using butt connectors part # DW05744-5 to seal them up.

- Can 2 Pin Harnesses 9651P and HM47965 Power Optronics Trailer Taillight Kit STL39RPGFor powering the Optronics trailer taillight part # STL37RPG there would be no difference between the two 12 inch 2 wire loops part # 9651P and the # HM47965. They are both 12 inches long and have the exact same two pin connectors.
view full answer... - Availability of LED Version of Aero Pro Trailer Taillight # ST36RBWe do have just what you are looking for. The part # STL36RPG is an LED version of the # ST36RB that has the 3-prong connector you want. The matching side to this is the part # STL37RPG.
view full answer... - Can Amber Light be Used as Turn Signal on Motorcycle Trailer?The Miro-Flex LED Turn Signal # MCL48AB can be used as an amber turn signal with your motorcycle trailer. It will work alongside the tail lights you referenced, Aero Pro - LH # STL37RPG and Aero Pro - RH # STL36RB, with the wiring you already have on your trailer. I've added links to review videos of these products for you to check out as well.
view full answer... - Recommended 3 Wire LED Replacement Option for # ST66RPGFor the LED version of the # ST66RPG taillight, you will want the Over 80", Aero Pro Submersible LED Trailer Tail Light, 2 Wire, 7-Function, 17 Diode, RH # STL36RB and LH # STL37RPG.
view full answer... - Picking Out Aero Style Trailer Taillights with 3-Pin PlugsWe used to carry the driver side as ST67RPG but it was phased out and we can't get it anymore but thankfully we have the part # STL37RPG for the driver side and # STL36RPG for the passenger side that is currently still available. These use the 3-pin plug like you want.
view full answer... - Replacement Trailer Light Recommendation for a 2004 Pro Team 175 Boat TrailerI tried to find pictures of your trailer so that I could determine what trailer lights it would have and could not find a solid picture that I could use to know for certain what you have. One picture looked very similar to the # STL36RPG and the # STL37RPG that you referenced so there is a great chance these lights would work. If your lights measure 7-7/8" L x 3-1/4" W x 2-7/8" D then these would work.
