Upgrading from older bulbs makes a big difference in visibility. This 6" x 3-9/16" x 2-1/4" right-side tail light uses six LEDs that stay bright and consistent across 9 to 14 volts. The LEDs draw little power yet throw a crisp red light for stop, turn, tail, and marker functions. That means clear signals even in daylight, no filaments to burn out, and a setup that lasts mile after mile.
Rain, road spray, or a dunk at the boat ramp—this light is built to handle it. Its hermetically sealed body with potted electronics meets IP68 standards for dust and water protection. The sealed design keeps moisture out and prevents corrosion inside the housing, so you can count on it no matter where the road takes you.
One sleek housing covers every requirement—stop, turn, tail, side marker, clearance marker, rear reflector, and side reflector. Having all seven functions built into one light makes wiring straightforward and helps ensure your trailer is fully compliant with lighting regulations. You get a cleaner install without extra lights cluttering the back end.
Mounting this light is simple and solid. It uses two standard 1/4"-20 carriage bolts (not included) for a surface install and connects through a 12" pigtail harness. Each wire is clearly identified—white for ground, brown for brake lights, green for right turn, yellow for left turn—so setup is quick with minimal tools required.
The rugged lens meets FMVSS 108 requirements for durability and safety. It resists cracking and road debris impacts, keeping your light safe through years of use. TecNiq backs it with a lifetime warranty, giving you confidence that this tail light is built to last as long as your trailer does.

Hi, everyone. Steven here with etrailer.com. Let's take a look at our TecNiq 7-Function Slim Line Taillight for the right hand side. So folks, again, this is TecNiq's 7-Function Slim Line Taillight, and it's able to meet all requirements for your stop, turn, tail side marker, clearance marker, rear reflector and side reflector, in a revolutionary cost effective design. Now again, this is the right hand side. If you need the left hand side or the driver's side, that is the side that would include the license plate light.
As you can see, this one does not have that. So again, that left hand, item number is TN39AR sold separately. Again, we are looking at the right hand side or passenger side today. Now, this is 6 inches long by 3 1/2 inches tall by 2 inches wide. And as you can see, I've got it pre-wired up right now giving us our running lights.
And let's see if we can show the brake lights here. Bear with me. All right. So yeah, whenever you hit your brakes, it would be brighter. And then same thing, your blinker would blink.
Let's go ahead and shut off the overhead lights in the studio and take a look at this in the dark. So, as you can see, very, very effective at getting your attention. And if we zoom out, same thing. So, as you can see, it's pretty bright. It's gonna get the job done.
It's gonna make you visible at all angles while you're driving and keep you safe, and keep other people on the road safe, alerting them of your presence as well. So again folks, we do carry both the driver and passenger side sold separately. And on the backside of this, you have two slots here. You would need two mounting carriage bolts sold separately that would go into your trailer frame and this would literally just pop right down onto those carriage bolts and it would hold snug in place with that plastic housing. So again, a great option. It is dust and waterproof. It's been hermetic-sealed to prevent dust and water from getting inside. And it has a nice durable impact resistant lens. And again, you have your side reflectors and everything, as well as your front reflectors as well. Runs on 12 volts. That that will wrap it up, folks, for our quick look together at this TecNiq 7-Function Slim Line right side assembly. I'm Steven. Reach out to us if you have questions or concerns, or if you're still confused about which side you need. Have a good one.
