Features to know about

Bright Interior Lighting Made Simple: 12 High-Efficiency White LEDs

When you want your space to feel brighter without wasting power, this surface-mount dome light delivers. It uses 12 high-efficiency white LEDs that put out 300 lumens while running on just 9 to 14 volts DC. The frosted acrylic lens spreads that light evenly, giving you clean illumination without harsh glare. It’s a solid upgrade for clear, consistent lighting that doesn’t strain your power system.

Clean, Streamlined Mounting: Low-Profile Round Design

No bulky housing or exposed screws here. This 4-1/2" round light mounts flush to the surface with hidden mounting holes that keep the install looking neat. At only 1" deep, it stays out of the way yet still provides full coverage. The included 8" sheathed pigtail keeps wiring tidy and protected for a simple, professional-looking finish.

Quick Control at Your Fingertips: Built-In On/Off Switch

You don’t need to wire in an extra switch—this light already has one built right in. Whether you’re adding accent lighting or a bright task light, the integrated switch makes it easy to turn it on or off right where you need it. It’s convenient, straightforward, and ready to use without extra parts.

Durable and Reliable for Demanding Use: TecNiq Quality Construction

Built for tough environments from trailers to marine setups, this TecNiq dome light is designed to last. The rugged housing protects the LEDs and wiring, and with efficient optical design you get strong performance every time you flip the switch. It’s dependable lighting engineered for years of use without the worry of fragile bulbs or corrosion.

Video Transcript for Review of TecNiq Trailer Lights - Interior Lights - TN89TR

Hi, everyone, Steven here with etrailer.com. Today we're looking at our TecNiq Dome Surface-Mount Light. It's a 4 1/2-inch round light with a white frosted lens and LEDs inside with a power switch. So, folks, again, I went ahead and took off this acrylic lens. It's frosted, it's heavy-duty. This way you can see the LEDs inside.

I did go ahead and power this up so you see just how bright it is with the lens, and I'm gonna go ahead and pop this in place. So, that's how you would do it. The mounting holes are inside of here all across the back, and it gives you an option to then, you know, mount it to wherever you need to, pop this frost it acrylic lens back in place, and then boom, you're ready to go, and now you've got light, right whenever you need it and where you need it. It does come with an eight-inch-long sheathed pigtail, and it's a great option if you wanna get light in different places where you're lacking light. And it does put off a lot of light, about four feet from the back wall here today, and as you can see, it's pretty bright.

So, 300 lumens of power is what it's putting out. Let's go ahead and shut this back off. And like I said, folks, 4 1/2 inches, round. It's about, oh, not quite one inch tall overall, right in the center. It's kinda hard to get a measurement on that without using calipers, but right about one inch tall, and again, you have a nice eight-inch-long pigtail here, black and white, ready to go.

Again, 12 LEDs, runs on 12 volts of power. That's gonna wrap it up for our quick look together, folks. I'm Steven, thanks for watching.
