Light will work as an exact replacement for:
Truck Lite # 44302R
Grote # 53252
Peterson # M417R-2
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.
Recessed-Mount Light
Recessed-mount trailer lights install underneath a housing or a grommet (A45GB - sold separately). These lights will extend into the mounting surface and require that a hole be cut into your trailer.

Bought these LED Stop/Tail lights for my new dump trailer. The factory stop/tails are mounted very low, and any car directly behind me blocks my lights from the 2nd or 3rd car behind me. So I mounted these new ones up as high as I could to let people know I am stopping or turning. I also mounted a side marker light so I could see where the trailer was while backing up at night. The factory marker lights are so low I can’t see them in my mirrors because they are blocked by the step on the drivers side and the spare tire on the passenger side. I am a retired 18 wheeler driver of 47 years.

I am in the process of renovating a 1966 Airstream. I wanted to upgrade the tail lights and the clearance lights. I found etrailer.com on a web search. I ordered the round 4" LED, rubber 4" grommet, and Oval LED clearance light. The round stop with grommet adapeted perfectly into the lens on the Airstream. I will feel so much safer now with the added visability. The lights are stellar.

We had a trailer that had old Grote anti-theft incandescent lights. The holes for them were right around 4.450” so there weren’t a lot of products we could find that would fit without major modifications. The Optronics lights with the thinner plastic flange mount did the trick! Thanks for stocking this product!
by: Jim Bob08/08/2016
I ordered a number of LED replacement components for my motorcycle trailer as well as a locking hitch pin and ball covers. I was very pleased with the shipment, product quality, and the attention to customer service (which came into play to make sure I did not incur shipping fees). Plus, the LED lights look great on my aluminum trailer. I will happily continue to do business with etrailer!
by: Megan01/18/2019
These light are great quality and shipping was extremely fast. I only needed one but purchased 4 and changed all my brake lights over to LED. I also appreciate the plethora of information with regard to issues installing this item. I had a little trouble fitting them back in my existing grommet, but your videos were very helpful. We have used etrailer several times. It's our go-to. Thanks again!

After about a year of using these brake lights, they are all working well! I took a trip about 600 miles away, and they worked extremely well allowing other vehicles to see my horse trailer and keeping us safe! I would definitely recommend this product to others!
by: Capt Ron T.09/11/2019
Ordered two, one had misguided plugs and would not work with my installed 3 prong male plug, the second finally plugged in
with difficulty, but the light worked when installed. Glad I ordered two as just needed one now, and the second was a spare for
future use. All through the order process the company offered great service and very quick shipping. Probably will use them again
in the future for needed parts in a hurry.

As stated, the one didnt work at all and was trashed. The other worked with difficulty plug in was mismatched but is still working.
by: J.l.07/27/2019
Although UPS is a little rough on packages, everything arrived unbroken. The only thing I didn't realize was that there was not any pigtails for these tail lights. Everything else was great. I'll see about chasing down the pig-tails from the local trailer dealer.

Have had 0 problems since installed. Much brighter appearance. Have since replaced tail and marker lights with 3 other trailers. Great job guys and gals.
by: Scott C10/30/2016
These lights are perfect! They have more LED's than the lights that came on my trailer and it looks better and is safer when towing at night.
Perfect parts and at a great price!
Thank you!

Perfect part and now a year later still perfect! These are a lot brighter than the old ones for sure and still look great! Excellent value, great service! What a great combination in a supplier! Order with confidence!

eTrailer.com did a Terrific Job for us! We needed tail lights for the Dune Buggy we're building in three different collors (red, amber & clear), and eTrailer was able to provide these for us in otherwise identical lights. We received everything we needed (all of the right appurtanances) and they look great! We were also impressed with the timeliness of etrailer.com's shipping and delivery, as we received our order far more quickly than promised or anticipated. The License Plate Holder and Light also look great! (Although the light is a little dim.) Overall high marks, and I would use eTrailer.com and Optronics again.
by: Scott 10/25/2023
Nice to get just one light by itself when that was all I needed. Great price and fast shipping.
by: Paul J.05/11/2011
While I haven't actually used them on a trip yet, I have to say that installing the LED stop/turn/tail lights was almost a no-brainer. Once I figured out the correct sequence, the lights easily slipped into the existing rubber housings. I plugged in the electrical connectors and they worked perfectly. Knowing that they'll never burn out is comforting.
by: Rick V.04/15/2013
I got two of these because one of the lights on my trailer had been cracked when I lent it out and subsequently the running light no longer worked. The lights that they replaced were standard incandescent bulbs and I didn't like the fact that I couldn't just replace the bulb as they were sealed units like these. Because these are led's I expect them to last quite a bit longer so the fact that they are sealed also is not as much of a problem and in reality should help them last longer.

Tail light assembly for Yakima Rack and Roll trailer. This is a relatively low cost item which includes light bulb sealed in a waterproofed unit. Item was delivered very quickly.
by: Vinny07/10/2015
We have been changing out the brake lights on all of our trucks with these led brake lights over the years. They are easy to see during the day and the lenses do not oxidize and wear out like the normal fixtures do. Plus you don't get the melted section in the middle of the light from the bulbs getting hot. Love these bad boys!
by: Eldon03/08/2013
This was to replace tail stop/turn light on my 5th wheel. Different pattern but works excellent and is actually a little brighter than what was replaced.
However, service and delivery was absolutely fantastic. Would highly recommend e-trailer service. I will definitely use e-trailer again.
by: ConnerCattleCompany08/11/2016
Good brake and turn signal light. Gave my old trailer some style. etrailer.com has great customer service and will take care of you.
by: William 07/06/2020
Extremely pleased with my purchase. I have a set of tow light, needed to replace the LED housing. The manufacturer of my lights did not sell the housing. I would have to purchase the whole thing again. So glad I found etrailer in my search. Housing was just like my OEM housing, and worked perfectly.
by: Stan N.06/11/2014
I checked with several RV parts locations in our area including CW and this product was not available. Etrailer.com made ordering so easy and what service! I received an immediate order confirmation and the shipping confirmation arrived very quickly too. I just received my delivery and the installation has been completed. Thanks guys for such great customer service!

I used this to replace a failed tail light on a Lance camper. It fit in the existing hole just fine. Easy installation, good price, quick delivery.

Product delivered on time and was packaged properly. Installed on a tow dolly and was an exact fit, making installation a breeze.

See what our Experts say about this Optronics Trailer Lights
- Trailer Wiring and Lighting Replacement for Trailer with 4.5 inch Red and 2.5 inch Amber LightFor a 4-1/2 inch diameter trailer taillight that can do stop/tail/turn functions we have the part # STL43RB which would work well. For a rubber grommet then we'd need the part # A45GB. Then for a pigtail harness you'd need the part # A47PB. For the 2-1/2 inch amber lights you'd want the part # MCL59AB and for a grommet for this you'd need part # A55GB. For a pigtail for this you'd want part # A46PB. Then for 4-way wiring sold by the foot you'd want the part # 16-4B-1.

- Compatibility of Optronics Trailer Tail Light # STL43RB With Trailer 4-1/2-Inch OpeningThe Optronics Trailer Light # STL43RB that you referenced can mount using rubber grommet # A45GB. But this light's overall diameter is 4-5/16-inches so this light unit would be too large to allow for grommet mounting in your trailer's 4-1/2-inch opening. However, my contact at Optronics confirmed that this mounting grommet # A45GB will fit a 4-1/2-inch rough opening and with it you can use the other light you referenced, part # STL101RB, which is 4-inches in diameter. If you need a wiring...

- Can Sealed 4 Round LED Trailer Light # STL43RB Be Used Underwater in Saltwater EnvironmentI spoke with my contact at Optronics and in order to use the Sealed, 4" Round LED Trailer Stop, Turn and Tail Light, # STL43RB, in the saltwater environment, you will want to use marine grease like part # L54FR on the Straight 3-Wire Pigtail Plug, # A45PB, and then seal around the plug with a silicone sealant like part # 0160297. This will help to prevent any water from getting into the light housing during the constant in and out of saltwater service that your boat gets.

view full answer... - Is the Optronics LED # STL43RB the Correct Replacement for Peterson 426 TaillightThe Optronics LED Taillight you referred to, part # STL43RB would indeed be a correct replacement for the Peterson 426 lamp you referred to. The # A45GB would be the correct replacement grommet and for a pigtail, you'd use part # A45PB. The LED replacement would be a great option, as they use a lot less power, would last much longer and are quite a bit brighter than their incandescent counterparts.
view full answer... - Replacement LED Tail Light For Pacific TrailerWe 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...
view full answer... - Recommendations For Adding Tail Lights To A Kuat NV 2.0 Bike RackThough you will need to have a 4 Flat on your 2001 VW Eurovan, and for this I do recommend the Curt # C56175, adding lights to your Kuat NV 2.0 is definitely a good idea. I went through all our options for adding lights to a bike rack or cargo trailer, and the Curt Auxiliary LED Indicator Lights # C53201 will be the good option, but there is a potential issue. The base of the rack is not the same length on both sides and the arm the swings up and tightens down on the wheel will give you...
view full answer... - Recommended Load Resistor for Installing Optronics LED Trailer Light STL43RBWhen high-efficiency LED type lights are installed in place of power-hungry incandescent bulbs it is often necessary to install a load resistor. The resistor turns some of the incoming power into heat and in doing so it mimics the higher power draw of an incandescent bulb. This will prevent the hyper-flashing common when LEDs are installed in an incandescent lighting system. For the Optronics Round LED Trailer Stop, Turn and Tail Light # STL43RB you can use their load resistor kit # ALEDRST1B...
view full answer... - Recommendation for a Bright LED Tail Light that Can Be Used on a MotorcycleRound LED Trailer Stop, Turn and Tail Light, # STL43RB, has 10 diodes in it that produce the light. If you are looking for more light, you may want to look at something with more diodes. The Round, Stop/Turn/Tail Light, # STL23CCRB, has 12 LEDs and a clear lens with the Miro-Flex design for maximum light output. It has the same dimensions as the STL43RB and can use wiring harnesses, # A45PB, or # A47PB.

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. If this is not the correct part, then send me a photo with the measurements of the light and we will get you what you need. The numbers and letters that are actually printed on the light are...

- Trailer Tail Light Replacement for a Trulite model 44 LED Tail LightFrom my research it looks like the Submersible LED Optronics Trailer Light # STL43RB is a comparable replacement light. It is 4-5/16" in diameter and has 10 super diodes that function as stop, turn, and tail signals. You can install the light using a Pigtail, like part # A45PB or part # A47PB, and a Rubber Grommet # A45GB. A sample installation video has been linked for you to use as a reference.
view full answer... - LED Replacement Light Recommendation For Bargman 68 Round 4-1/2 Inch Trailer LightsWe have four different round LED stop, turn and tail lights that will fit in the 4-1/2 inch diameter holes in your rear bumper. You could use the Optronics light, # STL23RB, # STL43RB, # STL53RCB or # STL23CCRB. These are 4 inch round lights, but they require a rubber grommet, # A45GB, that allows 4 inch round lights to flush mount in a 4-1/2 inch cutout. Lights # STL43RB and # STL53RCB are sealed, submersible lights if you are adding these lights to a boat trailer. All of these lights...
view full answer... - Tow Dolly LED Brake Lights Blow Stop Light Fuse on RV But All Other Lights Work FineThere could be a short somewhere inside one of the lights causing the problem. There certainly is not enough power draw from LED lights to blow a stop light fuse on a vehicle so it would have to be a short somewhere. If everything works fine with a trailer connected and all of the other tow dolly lights work as they should then all signs point to an internal problem with the lights. My recommendation is to replace the lights and inspect the wiring (just to be safe) and fix any broken or...
view full answer... - Installing Trailer Tail Lights with Two Wire Connections on 4-Way WiringThey are single function lights, so they can be used as running lights or stop/turn but not both. So for your trailer to be legal, you will need to run two on each side, one for the running light (brown wire of your 4-way) and one for the turn/stop light (green or yellow wire of your 4-way depending on side of the trailer). You will attach the power wire (green, yellow, or brown) to the red wire of your light. The white wire on your light will go to ground, so you will attach it to the...

- Troubleshooting 3 Wire LED Tail Light InstallationYour old two wire lights definitely used the mounting screw as the ground. Your new LED lights with 3 wires will be easy to transition. You will connect the running light wire and the turn/stop wire just as before, and then you will run the ground wire directly to your steel frame. A bad ground is most likely the issue with your fuses blowing. Make sure your ground wire to your frame is metal on metal and your 3 wire LED lights like # STL43RB with 3 wire pigtail similar to the # A45PB....
view full answer... - Can Bulb be Replaced on Peterson Red Flush Mounted Sealed Turn Signal Light 435800Peterson brake/turn signal light # 435800 is sealed and cannot be opened up to change out the bulb. I pulled one from the warehouse to verify this and cannot get the lens off (without breaking it) to access the bulb/interior of the light. What I recommend is to use an LED light, # STL43RB, because the LEDs will last much longer than a regular incandescent bulb. For a grommet use # A45GB and for a wiring harness use # A45PB.
view full answer... - What is Included with Optronics 4 Inch Round LED Tail LightThe Optronics 4 Inch Round LED Tail Light # STL43RB does not come with a pigtail. For a 3-Wire Pigtail with a 3-Prong Plug # A45PB is what you'll need. If you'd like the rubber grommet then # A45GB is what you're looking for.
view full answer... - Recommended Three-Prong Wiring Plug For Optronics Sealed Round LED Trailer Light # STL43RB We do have the three-prong pigtail you can use with the Optronics Trailer Light # STL43RB. You will need part # A45PB. This has the three-prong plug with 10 inches of wire.
view full answer... - Solution for Installing Optronics LED Trailer Tail Light on Trailer With Round 3-Prong Light PlugThe Optronics LED Trailer Tail Light # STL43RB is only available with this plug style. We do not carry the GROTE brand or have any lights like this that match the round plug. However, a simple solution would be to cut off your existing plug and use the # A47PB or # A45PB.
view full answer... - Could Optronics GloLight Trailer Taillight STL101RB Be Wired for Stop/Turn/Tail CircuitsThe GloLight LED Trailer Tail Light # STL43RB you referenced can be used for the application you mentioned. It's a dual intensity light which means that the lower intensity would cover the running lights and the brighter one would cover the stop and turn circuits. There isn't a way to operate the ring around the outside of the light separately. You'd want the harness part # A45PB to install the light. White wire is for ground, black wire is for running lights and red would be for stop...
view full answer... - Tips for Installing New Trailer Clearance Light into Rubber GrommetGetting light assemblies into the grommets can be somewhat challenging. We have found that if you insert the grommet first (like you did), and then put a light amount of grease around the grommet edge the light will slide in easier. If you check out the video I attached you can see one of our installers walk through this process. Fast forward to the 1:45 mark.
