This 4-5/16" round red LED light delivers clear brake, tail, and turn signals that stand out day or night. With seven diodes behind a durable polycarbonate lens, it’s more efficient and lasts far longer than incandescent bulbs. At 12.8 volts, it draws only 0.234 amps for stop and turn functions and just 0.033 amps for the tail light. That means bright, reliable lighting without stressing your wiring or draining power unnecessarily.
No need to worry about rain, washdowns, or launching a boat trailer—this light is completely waterproof and sealed tight. Its polycarbonate housing and lens are built to keep moisture out, keeping the LEDs safe and dependable no matter how wet things get. It’s designed for submersion, so it keeps working even in the toughest trailer environments.
The built-in weathertight connector protects wiring from corrosion and moisture where most lights fail first. It pairs with the AL45PWTB adapter (sold separately) to link to standard 3-prong plugs. Once connected, you get a solid electrical seal that won’t loosen or short out after a few miles on rough roads.
This light installs cleanly into a 4-1/2" diameter cutout using the A45GB grommet (sold separately). The recessed mount keeps it out of harm’s way while giving a factory look. If cutting a hole isn’t an option, there’s also an optional bracket (BK45BB - sold separately) that works with the same grommet for an easy exterior mount.
The tough polycarbonate housing resists impacts and wear from the elements, making it a solid choice for long-term use. The LEDs carry a lifetime warranty, and the housing itself is backed by a 3-year limited warranty—so you can count on this light to last mile after mile without dimming or cracking.

Today we're going to be taking a look at the Optronics LED trailer tail light. The round trailer tail lights serves 3 functions, such as your stop light, tail light and turn signal light. It's going to feature a sonically sealed water proof housing and lens unit that is submersible. It's a full LED system, LED's are going to make great replacements for incandescent lights. They're going to last longer, burn brighter, they're much more efficient. You don't have to worry about bulbs and you don't have to worry about burr filaments. When it comes to the construction, we're looking at a polycarbonate lens and housing.
The housing on the unit is going to be a grey color, the lens is going to be a red lens. This is designed to be a recess mount installation, with a mounting grommet. Grommets are sold separately. You can find them here at etrailer.com if you're needing one. The light will fit into a hole with a diameter of 4 and a half inches. Now, here on the back, it's got a really unique plug.
This is known as a weather tight connection point on the back. This does require an adapter part number AL45PWTB to work with the industry standard 3 prong plug. Now that adapter is sold separately and it's available here at etrailer.com as well. The light is department of transportation compliant. When we take a look at the dimensions, starting with the diameter, outer edge to outer edge, we're looking at a measurement of about 4 and 5/16 of an inch.
If we take a look at the thickness including the plug at the back, that's going to give us a measurement of 1 and 13/16 of an inch. Not including the plug, so just this portion up here, that's going to give us a measurement of about 3/4 of an inch. It's going to contain 7 diodes or 7 LEDs. The power draw for the stop and turn signal is 0.234 amps at 12.8 volts. For the tail light is 0.033 amps at 12.8 volts. Optronics is going to put a lifetime warranty on the LEDs.
We're going to go ahead and hook it up to our external power source, that way you can see what it looks like with power into it. Here we have that weather tight plug. Slides in right here and then it's got the locking tab. This is going to be the tail light function of the light. It sends out a nice consistent signal, allows plenty of light to come through. Again, it's going to contain a total of 7 LEDS. When we apply our brakes, you can see how the signal output increases for brighter light. It's also going to do that when we activate our turn signals. That's going to do it for today's look at the Optronics LED trailer tail light.
Ratings & Reviews
Direct replacement with no issues, excellent packaging and fast delivery.
Easy to order online, Items arrived during the expected delivery date. Have always had good luck with Optronics products. Just waiting for the truck to get back to the shop so I can replace the old incandescnt lights with the new LED lights.
I had to replace one burned tail light on my 2005 cargo trailer. I bought two and replace the other one as well. They work perfectly. The size and the 3 pins connction are the same as the original. A little downside is regarding the packaging. I would expect each light wrapped individualy to avoid the rattling in the box. See pics.
Exact match to the old light
They work great and we're fairly easy to install as a replacement for the old style brake lights with bulbs....
I have a Haulmark utility trailer. One tail light was giving me trouble and I tried fixing it but decided to just replace it with these. They are brighter and fit right in to the old grommet. They were a bit loose so I wrapped some e-tape around them and they are staying in place just fine. I also ordered the pigtails and soldered and heat-shrinked the connections - the factory connecting were "scotch-locks", which I hate. After I did this, I looked closely at the old lights and realized that there was a 3 prong plug which I might have been able to use rather than doing new connections and soldering them, but by doing what I did, I now have tight connections and I can easily replace the light if I ever have to (I got rid of the scotch locks). Yes, I could maybe have soldered the old connections and used the old plug, but it was constructed in such a way that I didn't realize it was there (I thought it was part of the light body). My picture shows the old light and the old plug disconnected from it and the new LED in place on my trailer. It works great - glad I did this. It's much brighter than the old light.
THESE ARE AWESUM. They even look good when off !! Cant wait to BLIND some tailgaters. Drivers who tailgate boat trailers need to be tazed. I ADDED a Sequential Turn module to each side making them even better. A 3rd brake light wire controls others so only E-Trailers Optronics blink. SUPER BRIGHT !! These pull no power at all so I run 30 LED units or hundreds of bulbs all around the 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 bought these lights for a boat trailer. They are very bright and we're easy to install. I would recommend to anyone looking for replacement lights
Perfect. Exactly what I wanted and needed. Fast shipping. Great communication! Thank you.
Best in class service…quick delivery and the right price.
SuperFast Shipping
Great service the exact replacement nee ded.
Great product if you have an odd ball trailer light set up like I do that requires a center mount position plug! Fast east purchase and fast shipping, great company to deal with!
This light was almost an exact match for the stock light that came on the camper. I bought 2 and replaced them both, and they seem to be a little bit brighter than the originals, which I am glad with.
This light was exactly like described. I purchase a lot on line and use amazon prime for free shipping. I could not find this light on amazon and was very impressed that etrailer.com had very reasonable shipping prices. Instead of gouging the cost was in line what normal shipping cost would be. The shipping and tracking were spot on and the lights were delivered as promised. A VERY good company to work with.
We are looking for a supplier of trailer parts .. they had what we needed.
We build aprox 60 trailers a year. I am going to take a good look to see what else we can get from them.
Identical size, shape & function to the original taillight on a 2-yo Master Tow dolly. Replacement taillight from the mfg didn’t fit the original taillight bezel. This one is an exact fit.
My experience with Etrailer was excellent again as always. Always appreciate the explanation and videos to confirm correct product and installation before purchase. Delivery is always awesome as well.
I have not hooked it up to power, but I'm sure it will work. THe only disappointment I had was the light I removed had a rubber pad to help seal the screw holes and wire entry to the back of my trailer to keep moisture out. This light does not have that and it is not available from your company.
Exact replacements for my old tail lights.Fit perfectly. They also solved the issue. Tho old tail lights were allowing the blinker current to back track through the clearance lights. One of tail lights had water in it and when it flashed the clearance lights flashed too.
While I've not yet installed these they look like good replacements for the OEM lights. They are the correct style, size and the screw hole placement seems to be correct. My only reason for giving them an average rating is that they don't come with any gaskets. The original lights have a gasket between the back of the light and the wall of the camper. While the light unit itself is sealed the wires come through a hole in the camper wall and without a gasket the possibility of leaks is there. I will likely buy some gasket material from an auto parts store and make my own. No, I don't think the camper sealant will work as well as a rubber gasket.
Shipped fast. Easy to work with.
Works as it is advertised.
