Features to know about

Brighter and More Efficient Lighting: Amber LED with Clear Lens

Older incandescent bulbs can fade and draw more power than they should. This 6-7/16" oval amber LED light solves that with a clean, efficient design. It uses 10 LEDs behind a clear lens to deliver bright illumination that stands out for both parking and turn signal functions. At 12.8V it only draws 0.243 amps for the parking light and 0.275 amps for the turn signal, so you get solid performance with minimal power use.

Built to Handle Water and Weather: Fully Waterproof Design

If your trailer ever sees water or road spray, this light holds up. The housing and lens are sealed and waterproof, making it a solid choice for boat trailers or other wet environments. You won’t have to worry about moisture getting inside or damaging the LEDs.

Straightforward Wiring and Setup: Standard PL-3 Connector

No need to fight with complicated wiring. The light uses a standard 3-prong PL-3 plug that works with either the right-angle pigtail (A47PB) or straight pigtail (A45PB), both sold separately. Once connected, it’s ready to run on any 12V DC system with clear identification of ground, running, and turn wires.

Clean Mounting Options: Recessed Fit or Bracket Mount

You can install this light recessed with the required A70GB grommet (sold separately) for a flush look that protects the housing from bumps. If you’d rather mount it externally without cutting a new hole, you can use the optional BK70BB bracket (sold separately) along with the same grommet. Either way, it fits neatly and stays solid once in place.

Long-Term Dependability: LED Durability and Lifetime Warranty

This Optronics light is built for longevity. The polycarbonate lens and housing are both tough and impact-resistant, and the LEDs last far longer than traditional bulbs. It even comes backed by a lifetime LED warranty for peace of mind every time you hook up.

Video Transcript for Detailed Breakdown of the Optronics LED Trailer Turn Signal and Parking Light

What's up everybody It's AJ with etrailer.com. Today we're gonna be checking out this Optronics parking and signal light. Just gonna go on the side of your trailer. It's gonna have a clear lens, but the LED lights on the inside are gonna be amber. Let's check it out. Today we're gonna be installing on our Big Tex flatbed trailer.

Now you come in closer, look at it. It's gonna have 10 diodes on it, so that's gonna help how bright it is. Now with the clear lens out front, it's not gonna already have that amber color that some other lights do. The LEDs themself are gonna light up amber. Let's install the light real quick.

We have our three prong connector here. Just plug it into the back of our light. Now, it's also gonna be able to be submerged in water. So if you're putting on a boat trailer, that's okay too. And it's DOT compliant.

So I'm gonna push it here in our grommet. Just like that. Now we're gonna turn on the lights and see how bright it is. It has the brake lights on there right now. We're gonna do a right turn And then we can go to taillights.

Taking a good look at the light. It is shine pretty bright there, brighter than the one we had in before. Now the light measure 6 5/16 of an inch by 2 1/8 of an inch. So make sure you measure your trailer, and make sure it's gonna fit in there just like this one. Now there's some different options for side marker lights. So another LED one would be this one. It has an a amber lens on it, so even when it's off, you can see it's that amber color and it has a mirrored background. So it's gonna be a little bit brighter than when we have installed right now. Also this is one that protrudes a little bit this light comes out. So it's gonna help with visibility, especially if the rail up here, this can stick out a little bit further so you or anybody on the side can see it easier. Then we have incandescent, which we usually recommend you replace with an LED because this is an old bulb style. It works just fine, but it's not gonna last as long as the LEDs or be as bright. Overall, this is gonna be a good LED light to add to your trailer if you're replacing one. It's definitely be an upgrade. If you're going from incandescent to LED, this is gonna be way brighter and last way longer than those bulb lights. Well, I think that does it. Thanks for hanging out. I hope this helped.

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



by:

Perfect. Exactly what I wanted and needed. Fast shipping. Great communication! Thank you.



by:

Best in class service…quick delivery and the right price.

SuperFast Shipping



by:

Great service the exact replacement nee ded.



by:

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!



by:

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.



by:

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.



by:

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.



by:

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.



by:

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.



by:

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.



by:

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.



by:

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.

by:

Good quality, but guess I misunderstood the listing, these are amber and I was looking for clear lens red for tail lights



by:

The light fits perfectly in my Ranch Hand rear bumper. It is actually higher quality than the light that originally came with the bumper.

Thank you, Amy at etrailer.

See what our Experts say about this Optronics Trailer Lights

  • Availability of Oval Clearance Light with Clear Lens
    Hey Dariel, the closest option would be the Optronics LED trailer light part # STL72CAB and the # STL111ACB which are both designed to install with the grommet # a70gb.

  • Is Load Resistor Needed To Replace Incandescent Front Turn Signal W/ Optrionics LED Turn Signal?
    Yes, you will need to use load resistors to keep the Optronics LED Trailer Turn Signal Lights # STL72CAB that you are installing on the front bumper of your vehicle from hyper flashing. I recommend using the # ALEDRST1B as it has the 3-prong plug needed to plug directly into the light, and can then be wired to the truck. You will need to connect the white wire to the ground wire on your truck, the black wire to the running light wire on your truck, and the red wire to the turn signal...

  • Trailer Stop, Turn, Tail Light With Clear Lens
    I may have an option for you but there is not a tail light available with a clear lens or housing that is exactly the same as the Optronics LED Trailer Tail light part # STL72RB. The department of transportation does require brake lights to be red so it is uncommon for the lens to be clear on the stop, tail and turn lights.There is the Optronics LED Trailer Turn Signal and Parking Light part # STL72CAB with clear lens but it lights up amber for turn signal and parking. You will need the...
