When you need to be seen in all conditions, this TecNiq 4" round light delivers. It uses 10 LEDs—8 red and 2 white—to power its stop, tail, turn, and reverse functions. The clear lens keeps the light crisp and visible from a distance, helping others spot you sooner whether it’s day or night. Operating from 9 to 14 volts DC, it stays bright and reliable without flicker or dimming.
If you’re tired of lights fogging up or failing after a few wet trips, this one’s built differently. The entire housing is hermetically sealed to block out dust and water completely. That means it’ll hold up in rain, mud, or washdowns without corroding or shorting out—so once it’s mounted, you can forget about it.
Rough roads and heavy use can crack or dull lesser lights, but this light’s durable impact-resistant lens keeps it protected. It’s engineered to exceed FMVSS 108 standards for safety and performance, giving you confidence that it can handle vibration and debris without failing or fading.
Swapping out old lights doesn’t have to be complicated. This model uses a flange mount design that fits standard mounting holes, so it installs cleanly without drilling new ones. The tripole connector makes wiring straightforward too—plug in, bolt down, and you’re ready to go.
TecNiq backs this light with a lifetime warranty, showing how confident they are in its build quality. Once installed, you can count on consistent performance for years without worrying about replacements or maintenance.

Hi everyone, Steve here with etrailer.com. Let's take a look at our TecNiq high visibility stop turn taillight. It's a four inch round flange mount and you're gonna have 10 LEDs power in this eight red ones and two white ones in the center for reverse. Now this is a durable impact resistant lens. It meets all FMVSS 108 standards, and it fits standard nine holes. So overall, including the flange is five and a half inches diameter, but the red light itself is four inches.
And on the back you do have two spots for two different tri pole plugs sold separately. And that's gonna be for your reverse and your stop tail and turn lights as well. Now I do have some wires here as you can see, I do have a way to kind of test this today together. So let's go ahead and take a look first at the reverse light. As you can see, super bright white.
It's gonna be highly visible at nighttime and at daytime alike. And if we go over here, let's do the turn signals. So that's your running slash turn and then the brake lights, bear with me here. There we go. So running lights, sorry, running lights.
And then the brake lights are brighter. So I do wanna try to do this with the lights off as well so bear with me here. And again, that would be your running lights. Then your turn slash brake lights, as you can see, much, much brighter. So again, folks, you have a great option here as far as mounting this again with the three screws sold separately, but again, you most likely already have those as this would be mainly a replacement light, most likely.
Folks, if you have any questions about this or any of the lights, we care, reach out to us, we're here to help you. I'm Steven, thanks for watching and stay safe while you're towing.
