Features to know about

Brighter and Longer-Lasting Visibility: Energy-Efficient Red LED

This 1" round LED light puts out a clean, bright red glow that’s easy to see at night. It functions as both a clearance and side marker light, helping others spot your trailer from a distance. The premium LED is vibration resistant, rated for up to 100,000 hours, and draws only 0.06 – 0.08 amps from a 9V – 14V power source. That means less strain on your system and fewer replacements down the road.

No More Water Damage Worries: Fully Submersible, Sealed Design

Whether you’re backing down a ramp or driving through rain, this light stays protected. The housing and lens are sealed together to form one waterproof unit, meeting IP68 standards for dust and water resistance. Inside, TecSeal urethane potting shields the circuit board from moisture better than common epoxy. It’s built to handle regular submersion without letting water or corrosion get in the way.

Full Coverage for Safer Towing: PC-Rated 180-Degree Beam

Visibility on the road matters, especially in low-light conditions. This PC-rated light throws a 180-degree arc of red light, visible from the front and the sides. Mounted properly, it doubles as both a clearance and side marker light—so you get complete coverage with just one compact unit.

Tight Install Spaces Made Simple: Compact and Easy Mounting

At 1" in diameter and 7/8" thick (3/4" diameter without the grommet), this light fits neatly anywhere you need extra visibility. It installs in a standard 3/4" hole using the included grommet and connects with an 18" long, 2-wire pigtail—black for power and white for ground. The durable, UV-resistant polycarbonate lens holds up to sunlight and impacts, delivering a clean look that lasts.

Video Transcript for All You Need to Know About the Mini Clearance/Side Marker Light w/ Grommet

Hello, everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at this TecNiq recessed mount, red LED side marker trailer light. Now, this is a nice, small, round LED light that'll serve as a side marker and clearance light for your trailer. It is a sealed waterproof housing and lens unit. It is IP 68 graded.

Does use a military-grade construction of the circuit board. Has urethan potting, which will offer better protection than common epoxy potting. And the LED is a premium LED, which is energy efficient, long-lasting, and vibration resistant. It is rated for up to 100,000 hours of operation. It has a durable UV resistant lens over it, and it is a clear lens over one red LED.

Now, this is compatible with 12 volt DC systems. I am gonna, in a minute here, we're gonna hook this up to some power just to show you how bright the light is. It is a recess mount installation. Comes with the included rubber grommet. Does require a 3/4 inch diameter cut-out for it to fit into.

And we also even sell a stainless steel trim ring for a finished look if you want, and it's listed on this product page as a related product. It is a two-wire harness. Hardwires to your application. It includes a white ground wire and a black power wire. The wire length is about 18 inches.

Now, this does meet or exceed the FMVS or the Federal Motor Vehicle Safety Standards, 108 standards. It is a PC-rated light, produces 180 degree beam when it's properly installed. Specs on it, the diameter of the light, it's gonna be right at one inch, and the depth on it is right at 7/8 of an inch. Input voltage is nine volts to 14 volts. And the power draw is .06 to .08 amps. So, we're gonna do now is hook it up to some power. And once we got it hooked up, I can turn on the power, and you'll be able to see the single LED, red LED. Gonna turn off the overhead light here just so you can see. For one LED, gives off a nice bright light. And I'll go ahead and turn back on our overhead lights, and turn off our power. But that should do it for the review on this TecNiq recessed mount, red 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!
by:
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

That is great to hear! I am glad the process was easy and I hope the install was as well. It looks great on your vehicle!

by:
Product itself is great. I'm not familiar with trailer wiring, so if there is a standard wire gauge that is typically used that's on me for not knowing it, but it would be nice if it were included in the product description. Aside from that, I am extremely satisfied with my item.
