Features to know about

Brighter and More Efficient Lighting: Amber LED with Clear Lens

Older bulbs just can’t compete with the clean, bright output of this premium LED. With a 9V–14V input range and a power draw of only 0.03–0.06 amps, it gives you strong illumination without pulling heavy current. The clear lens over the amber LED keeps visibility crisp while maintaining low power use. Rated for up to 100,000 hours of operation, it’s built to last for years of consistent performance.

No More Water Damage: Fully Sealed and IP68 Rated

Water intrusion ruins lights fast, but this one is sealed tight. The waterproof housing and lens are bonded into a single unit and filled with TecSeal urethane potting for complete circuit board protection. That design makes it IP68 rated—dustproof and fully submersible—so it stands up to rain, washdowns, or full immersion without a problem. Perfect peace of mind if your trailer ever hits the water.

Better Visibility from All Angles: PC-Rated 180° Beam Pattern

Visibility matters, and this light’s PC rating means it throws light in a full 180-degree spread—90 degrees to either side of centerline. That coverage lets it act as both a clearance and side marker light when mounted correctly, so others can see you head-on or from the side. It meets or exceeds FMVSS 108 standards, giving reliable output wherever it’s installed.

Compact Fit and Quick Mounting: Recessed 3/4" Design

Tight spaces aren’t an issue here. The light measures just 1" in diameter and 7/8" thick, fitting neatly into a standard 3/4" mounting hole with the included grommet. Its compact shape tucks away cleanly while still delivering serious light output. The 2-wire design with an 18" pigtail—white ground and black power—keeps wiring simple and straightforward.

Built to Handle the Elements: Durable Construction That Lasts

From UV rays to vibration on rough roads, this light is made for tough use. The UV-resistant polycarbonate lens resists fading and cracking, while the military-grade circuit board construction keeps everything stable inside. Whether it’s heat, moisture, or movement, this small round light keeps shining strong mile after mile.

Video Transcript for An In-Depth Look at the Mini LED Side Marker Boat Trailer Light

Hello, everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at the TecNiq recessed mount, mini amber LED, side marker trailer light. Now, this is a small, round LED light that'll serve as a side marker and clearance light for your trailer. Does use a nice sealed weatherproof housing and lens unit, and it does have an IP 68 rating. Does use the military-grade construction of the circuit board.

Uses urethane potting which offers better protection than the common epoxy potty. The LED is a premium LED. It's energy efficient, long-lasting and vibration resistant. And it is rated for up to 100,000 hours of operation. The lens is a durable UV resistant lens, and it is a clear lens over an amber, one amber LED.

And this is compatible with 12 volt DC system. It is a recessed mount installation. Comes with the included grommet, and it does require a 3/4 inch diameter cut-out for this light to fit into. We do also offer a stainless steel trim ring if you might want a nice finished look on it. We do sell that separately on our website and it is listed on this product page as a related product.

The wire harness on this is a two-wire harness. It'll hardwire to your application. It includes a ground wire and a power wire. The wire length on this is about 18 inches. And this is a PC-rated light, which will produce 180 degree beam when properly installed.

And it does meet or exceed the Federal Motor Vehicle Safety Standards. Now, I am gonna hook this up to some power just to show you how bright it is. But before I do that, I wanna give you some dimensions. The diameter on this is right at one inch. Total depth, front to back is right at 7/8 of an inch. Input voltage, nine volts to 14 volts. And the power draw, .03 to .06 amps. So again, what we're gonna do is we're gonna go ahead and hook up our two wires. And once we got them hooked up here, go ahead and turn on our power. And with the power on, you'll be able to see the amber LED light. So, I'll go ahead and turn off the overhead lights so you get a better view of it, and you can see how bright it is. And it is a clear lens with an amber LED. Go ahead and turn back on our overhead lights. Turn off our power. But that should do it for the review on this TecNiq recessed mount, mini amber LED, side marker trailer light..

These clearance lights are an exact replacement for those on my Wells Cargo trailer, whose grommets had rotted from exposure to the sun. Etrailer's list of their product's specifications made it easy for me to order the correct part. Shipment was immediate. I'm a happy repeat etrailer customer!

Exactly what I needed and a perfect fit. eTrailer had them shipped and delivered within a few days, which was great! As always, great product selection and service!
by:
Matched the bulbs in my shoreland’r trailer perfectly, the plugs were a different size. I just heat shrink soldered the new one on. Probably a better connection anyway. No problem
