Features to know about

Brighter and More Efficient Lighting: Long-Lasting Red LEDs

This V-shaped identification bar uses three premium red LEDs that deliver bright, clear light with minimal power draw. The LEDs are rated for up to 100,000 hours of operation and run efficiently on 9V–14V DC, drawing only 0.07–0.09 amps. You’ll get strong visibility while keeping electrical load low—perfect for a setup that you can trust trip after trip.

Stay Visible and Compliant: Over-80-Inch Identification Light

When your trailer measures 80" or wider, proper rear identification lighting isn’t just helpful—it’s required for safety compliance. This light meets or exceeds FMVSS 108 standards and clearly marks wide trailers so other drivers can see you in low light or from a distance. The V-shape design fits neatly along a rear V-bend cross member, giving you a clean, professional look that also improves safety awareness on the road.

Built for Harsh Conditions: Fully Submersible and Waterproof

Water exposure is no problem here. The housing is sealed to an IP68 rating, and the TecSeal urethane potting protects the military-grade circuit board far better than standard epoxy. Whether you’re backing into the water or driving through rain, this light resists moisture and corrosion while keeping the electronics completely protected.

Durable Construction That Lasts: Impact-Resistant Clear Lens

The clear UV-resistant lens is built to handle vibration and impact without cracking or fading. Its rugged build keeps the LEDs protected so the light stays bright even after years of use. This durability makes it a dependable upgrade for anyone who wants strong, consistent lighting without dealing with bulb failures or fragile housings.

Simple Setup Anywhere: Surface-Mount Installation

You can mount this 12-15/16" long by 2" wide by 1/2" thick identification bar directly to your trailer surface—no complicated brackets or bulky housing needed. With 9" between mounting holes and a 58" wire lead, it’s easy to position and connect exactly where you need it for clear rear visibility every time you’re on the move.

Video Transcript for Complete Breakdown of the V-Shaped Identification Light Bar for Boat Trailers

Hello everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at this V-shaped clear ID light bar for over 80 inch wide boat trailers. Now, this is a V-shape ID light, which will function as a rear identification light bar on boat trailers that are wider than 80 inches. And it is required by law to have a rear identification light when the trailer is wider than 80 inches. This is a nice low profile design, so it allows for installation in tight spaces.

And they do use sealed waterproof housing and lens unit, which is submersible. It does have an IP 68 rating and that means it's resistant to submersion up to maximum depth of five feet underwater for up to about 30 minutes. Now, they do use military-grade construction of the circuit board on this light. Uses a urethane potting, which offers better protection than the common epoxy potting. And the LEDs they use on these lights are premium LEDs.

They are energy efficient, long-lasting, vibration resistant. They are rated for up to 100,000 hours of operation. Now, at the end of this video, I am gonna hook this light up to some 12 volt power to show you how bright it is. It is a durable polycarbonate housing and lens. Now, this is a clear lens but it is over three red LEDs.

It is compatible with 12 volt DC systems, and it is a surface mount installation. Now, the hardware to install it is not included. There's two holes here that the hardware would go through to hold it into place. It does hardwire to your trailer. It's a two-wire design, a power and a ground wire, and they give you a wire length of about 58 inches.

Now, this light does meet or exceed the Federal Motor Vehicle Safety Standard 108 standards. Few specs on it, the input voltage is nine volts to 14 volts. Power draw is .07 to .09 amps. So, what I wanna do now is give you some measurements and then we'll hook it up to some power. The length from this end to this end, put a ruler on it. Now, this is a 13 inch length ruler, so it's just under 13. It's right at 12 15/16 of an inch. The height when this is installed is gonna be right at two inches tall. And the thickness of this light is only gonna be right at about a half an inch thick. Now, the distance between those two mounting holes we mentioned, if you go center to center is right at nine inches. So, what we're gonna do now is we'll go ahead and hook up our ground wire, and we'll hook up our power wire. And then with those hooked up, I'll go ahead and turn on the 12 volt power, and there you can see the lights light up. I'll go ahead and turn off the overhead lights, and there you can see the clear lens with the red LEDs. And what I'm gonna do is actually then zoom back out, and you can see it at a wider distance how bright those lights are. Turn back on our overhead lights. Go ahead and turn off our power. But that should do it for the review on this V-shaped clear ID light bar for over 80 inch wide boat trailers..

Good product and great price.



by:

Diagram was accurate and helpful. Perfect fit



by:

Just what we needed, works great.



by:

Smaller than my original light, less than I preferred but will work



by:

Looks great and working great after being in salt water almost every week.



by:

Product appears to be well made and fits my boat trailer perfectly!



by:

The old light bar was brutal and one light didn’t work replaced it with the new bar very happy hope it lasts a long time



by:

3 LEDs with sealed connections. Much brighter than previous identifier light on trailer



by:

I BROKE THE ONE ON THE TRAILER AND WAS WORRIED ABOUT A REPLACEMENT DU TO THE WIERD DESIGN, BUT eTRAIER CAME THRU AGAIN



by:

Worked fine, and fit the boat trailer "vee" very well. Did not come with screws. Took a while to get it.



by:

Light lasted about 3 months
Water entered
in the sealed wiring and had to be replaced



by:

The light still works great after being dipped in salt water many times .



by:

The part is perfect, noticed that was packed and shipped the same night! Looking forward on making more business since I might have few more items to get my trailer up to date, thank you for your business!!



by:

Great concept. I had gotten a boat trailer with a straight ID light bar installed on the V, and it had broken where it didn't line up with the steel beam. This v-shaped light is perfect, and the price is a bargain.



by:

The light shorted out after first use. Plugged the harness back in after launching a boat and it stopped working. Changed out all the wire connections and it didn’t work. Seemed to not be waterproof at the light. I think I just got a faulty one. Will still do business with etrailer, not their fault.



by:

Would not fit the trailer. Never used



by:

Great light for the back of my boat trailer.
I purchased this after having issues with the OEM light. This is a significant upgrade in brightness and overall appearance.



by:

Just more BLING.....



by:

I believe I sent this one back because it didn't work to replace the one with the chrome backing plate.



by:

Great product



by:

On time. Knew the new light was coming, so I could put a plan in place to install.
Nice customer service lets you know every step of the way!

I installed this light bar to replace the old one on my 1993 boat trailer. I did it when I replace the side marker lights and brake lights; all LEDs, and all from eTrailer. The mounting holes did not align with those that it replaced so I had to drill new ones. That said, I would have found it remarkable if they actually did align on a 32 year-old trailer, so that is a non-issue. There was plenty of wire to run and tap into the brake/marker lights without problems.

These lights are very bright, submersible, and definitely will help those behind you see you. That is all you can ask for.

See what our Experts say about this TecNiq Trailer Lights

  • Recommended Replacement For A Venture S.S. Rear Identification 3-Light Bar # 45000
    Hey Ken, The closest option we currently offer to the VENTURE S.S. Rear Identification 3-Light Bar #45000 would be either the TecNiq V-Shaped Identification Light Bar for Boat Trailers # TN73MR (clear lens - red LED's) or # TN23MR (red lens). These have a 9" mounting hole spacing instead of the 7-3/4" hole spacing that your current light has. You can just fill in the old mounting holes with some RTV sealant from your local hardware store and use self-tapping screws to drill into the frame...
