Features to know about

Brighter and Longer-Lasting Lighting: 3-Diode LED ID Bar

Old incandescent lights fade fast and soak up power, but this LED identification light bar changes that. With three red LEDs behind a clear lens, it delivers a strong, even glow across the back of the trailer while drawing only 0.022 amps at 12.8V. The LEDs last up to 50 times longer than standard bulbs, so there’s no need to worry about replacing filaments or dealing with dimming over time. It’s efficient, dependable light that keeps you visible on the road.

Built for Water Exposure: Fully Submersible, Sonically Sealed Design

If your trailer ever sees wet roads or boat ramps, this light is made to handle it. The lens and housing are sonically sealed into a single waterproof unit that keeps out moisture and protects the circuit board and diodes from damage. It’s truly submersible, so you can count on it to work reliably even after repeated dips in the water.

Durable Construction That Holds Up: Polycarbonate Lens and Housing

Rough conditions can crack ordinary lights, but not this one. The polycarbonate lens and housing give it strong impact resistance while keeping weight low. Even with bumps and vibrations from towing or loading, the construction stays solid and intact, keeping the LEDs safe inside.

Clean, Simple Installation: Surface Mount with 2-Wire Pigtail

Getting it mounted is straightforward. The light surface-mounts using holes spaced 16-1/8" center to center, and the simple two-wire design makes wiring easy—one power lead and one ground wire. At 17" long by 1-3/8" tall by 1" deep, it fits neatly along the rear frame without sticking out awkwardly.

Designed for Wide Trailers: DOT-Compliant P2-Rated Coverage

This identification light bar meets DOT requirements for trailers over 80" wide. Each diode produces a P2-rated beam pattern with a 45-degree spread on either side for clear rear visibility. It adds that required triple-light signal across the back so other drivers can spot your trailer right away in low light or bad weather.

Video Transcript for Identification Light Bar for Trailers over 80" Wide Review

Hi, I'm Shane with etrailer.com. Today, we're going to be taking a look at, I'm going to show you how to install Optronics 3 Diode LED Identification Light Bar on our flatbed trailer. It's going to function as a third tail light. You can see we're going to have three LED lights. It's going to be 17 inches long by an inch and three eighths, by one inch. It's going to be fully sealed, and waterproof.

There are other options for these lights, you can also get them with a clear lens, and you can get them either longer or shorter, with more diodes or less.You can also get these to function as a brake light, as well as a running light. For this particular light, this is only going to function as a running light or a third running light. It's going to be a two wire design. You're going to have your ground wire and your power wire. Again, they're going to be LED.

What's nice about the LEDs over the incandescent, is they're going to last much longer. With the incandescent lights, you have to change the bulbs when they blow out. With these, you have no light bulbs to change.The lenses are constructed in polycarbonate material, so they're going to hold up in all weather conditions. They're going to mount .. two mounting locations.

You're going to have one here, and one here. It's going to come with the hardware. Now that we've gone over some of the features, let's show you how to get it installed.For this particular installation, we're going to be replacing the light. We're already going to have the power wire ran back. If you are adding the third brake light and you don't have one previously, or didn't have one previously, what you're going to do is you're going to take the power wire from your brake lights that are already on there, and you're going to run one from each side back to wherever you're putting this light on.

Then you're going to tie into the black wire.These are my wires coming from my two lights, what we're going to do is we're going to strip these back. I'm going to add on the heat shrink butt connector, and these don't come with your lights, but I highly recommend them because your wires are going to be outside, open to the elements. This will help protect your connections from corroding. We'll take your other one, we're going to strip this one back just a little bit more. It doesn't really matter which wire you strip back, or which wire you add on to. What we're going to do is we're going to add on our black wire to one of them.So like that. And then the other end of our butt connector. Strip it down. Go ahead and take our heat source and heat shrink that butt connector. If you don't have a heat gun, you can find these here at etrailer.com also. I'll take our ground wire and push it in like that. And the kit's going to come with hardware. You will have a small nut here to go on the back. Go ahead and tighten those down. Then for our ground wire, we just need to make sure we're grounding it into metal. So we'll take a self tapping screw, and you can see our metal frame right here.This is a good place to do it. And then take any extra wire that we might have, and bundle then it up. Zip tie it if we need to. Make sure we don't have any wire hanging down that could potentially get caught on anything. Then we can test it out. We'll make sure it's working correctly.

These lights are well made and look great. They are a direct replacement for the older version I have. Tinted them to match the trailer. They were very easy to tint as the light surface is very flat.

Excellent experienceetrailer provided me excellent recommendation for the boat trailer application I have, but more important to me they were lower that anyone i found on the web including ebay. I payed no sale tax and no shipping. Delivery was within days of ordering with excellent comunication from their part.



by:

I made this purchase for my son's boat trailer. I ordered on the Monday before Thanksgiving and it arrived the day before. My son was so excited he went out and hooked it up to his truck battery to show us how bright it was. He is very pleased!



by:

Second time using etrailer. Ordering ( shopping ) is easy. None of the local supply stores have the selection, or price. Etrailer always has exactly what I need. Items ordered delivered promptly and packaged well. Thank you all for running an awesome business.



by:

Glad I made the decision to switch to LED! Much brighter, and more reliable than the ole incandescent bulbs. No worries about bulbs vibrating out of their sockets.

Great! No more wiggling the old incandescent bulbs to get it to light up, and no more pull overs by law enforcement. Glad I made the investment to switch to LED! As a regular etrailer customer...Thank you!



by:

It's a good product. Finished installation is clean, almost invisible against the white frame of my trailer. Sealed waterproof LED's means that it should never need any repairs or have any burned out lights. It's much nicer than the flimsy tin three-light bar I replaced.



by:

Looks sharp, very bright and the clear plastic is still clear. I did take some other people's advice and since my trailer is white I used white cauk behind the light to cover any scratches and the wire hole. I then used clear cauk to seal around the light itself to keep moisture out.
