Features to know about

Bright, Even Interior Lighting: 12 High-Efficiency White LEDs

This round surface-mount light delivers a clean, bright glow powered by 12 high-efficiency white LEDs. With 300 lumens of output, it lights up work areas, storage spaces, or cabins without harsh hot spots. The frosted acrylic lens evens out the beam so the light spreads smoothly across surfaces instead of creating glare or sharp edges.

Streamlined Look and Simple Mounting: Sleek 4-1/2" Surface Design

Installation is straightforward with its slim 4-1/2" x 1" housing and hidden mounting holes. The surface-mount style keeps things neat and low-profile, perfect for spots where you want lighting that blends in rather than sticks out. It comes pre-wired with an 8" sheathed pigtail for easy connection to your 9–14V DC system.

Reliable and Efficient Power: Low Draw Across 9–14 Volts DC

This light is built for dependable performance on standard 9–14V DC power. The LED setup delivers strong illumination while keeping current draw low, so it works efficiently without taxing your electrical system. No switch is integrated—just clean wiring and steady light when powered.

Durable for Demanding Environments: Rugged TecNiq Construction

Made by TecNiq for tough service across trailers, marine setups, and emergency gear, this dome light holds up under hard use. The solid build, sealed components, and quality LEDs mean it keeps shining where cheaper lights fade or fail. It’s a smart upgrade for anyone who wants bright, efficient lighting that lasts.

Video Transcript for Review of TecNiq Trailer Lights - Interior Lights LED - TN79TR

Hi everyone. Steven here with etrailer.com. Let's take a look together at this TecNiq dome surface mount light. It's gonna be four and a half inches round in a diameter. It's a white color with LEDs and there's no switch included. So folks, this is powered by 12 high efficiency LEDs.

And as you can see, the frosted acrylic lens comes right off. It has a couple of clips on there, or tabs rather molded into it that match up and hold it in place. So as you can see, you got the nice LEDs and then of course your mounting holes and that's how you would mount it. No hardware included. And I do want to go ahead and pop this back in here so we can get this powered on and show you what it looks like when it's in use.

So bear with me here while I snap this back in place. (lens snapping) So there you go, you just walk it around like I did and it pops right in place. You do have two eight inch sheath wires that are pre-stripped. And of course black is power and white is ground. And again, running on 12 volts.

So let's go ahead and power this on. And I will shut off the overhead lights in the studio here today so you can get a better view. So this is pretty bright, honestly, looking down at it, it's kind of not really blinding, but it's super bright. And I will go ahead and back out to a different camera view real quick. So far away you can kind of see it is putting off some real good light here for just how small it is.

But spinning around to the wall behind me, it's about two feet from the wall right now. And here it's about four feet from the wall, give or take. And this is about as high as my face here, so about four feet off the table. So I will go ahead and turn the overhead lights back on. So again, folks, a nice option if you're looking to either replace a light or add one, maybe in a hallway or in a room, putting off some nice light. This again is the TecNiq dome surface mount light, four and a half inches round. I'm Steven, thanks for watching.
