Features to know about

Bright, Efficient Lighting That Lasts: Red LED Output

This 1" diameter light uses a single red LED that’s built to run up to 100,000 hours. It draws just 0.06–0.08 amps at 9V–14V, so it stays bright without pulling much power. The red lens over the red LED gives off a clean, even glow that stands out clearly as a clearance or side marker. It’s energy efficient, long lasting, and vibration resistant—ideal for keeping your trailer visible every time you’re on the move.

Built to Handle Water and Weather: Fully Sealed and Submersible Design

Moisture is no match for this light’s sealed, waterproof construction. The housing and lens are sonically bonded into one solid unit, creating an IP68-rated barrier against water and dust. Inside, the circuit board is encapsulated in TecSeal urethane potting for full protection from corrosion or moisture damage. Even when submerged, it keeps shining reliably without fogging or shorting out.

Better Coverage and Visibility: PC-Rated 180-Degree Beam

Visibility from all angles is key for safety at night. This PC-rated light produces a 180-degree arc of red light—90 degrees on either side of its centerline—so it can serve as both a clearance and side marker light when mounted at a 45-degree angle. That wide beam pattern helps your trailer stand out from multiple viewpoints, improving awareness on the road or at the ramp.

Simple Mounting in Tight Spots: Compact Recessed Fit with Long Pigtail

Space is rarely generous on a trailer, but this compact round design installs easily using the included grommet in a standard 3/4" cutout. At just 7/8" thick, it sits flush and protected from bumps or snags. The 20' hardwired pigtail gives you plenty of length to route wiring neatly without struggling for reach, making setup straightforward even on longer trailers.

Tough Enough for the Long Haul: Durable Materials and Safety Compliance

The durable polycarbonate housing is UV-resistant and impact resistant for lasting clarity and strength in outdoor conditions. Built with military-grade circuit board construction, it’s made to handle vibration and rough use day after day. The light meets or exceeds FMVSS 108 standards, so you know it performs up to safety requirements every time you tow.

Video Transcript for Review of TecNiq Trailer Lights - Clearance Lights Red LED - TN53MR

Hi, everyone, Steven here with etrailer. Today we're looking at a mini clearance or side marker light with included grommet. It's a submersible red LED light with a red lens, and you get a nice 20 foot pigtail included. So folks, this may be small, but it is super, super bright, super brilliant, and it does come with the grommet. You would just push this in place once you got it in your trailer frame, and that's gonna smug it up and hold it in place. Now, as you can see, it's super bright.

It's almost kind of shown through my finger, through my fingernail there. So pretty bright and brilliant, and it does have a 20 foot long pigtail. I've got it kind of wired up today. It just simply uses the bullet style connectors. I'm gonna go ahead and wire this back up, so we can shut off the overhead lights in the studio, and give you a little better view.

Now, I apologize ahead of time. Sometimes the auto focus wants to kick in when it gets dark, so I apologize for that. Here we go, zoomed out. You can see a lot better. Again, this is a one inch diameter light.

It's about 7/8 inches thick on the side, so it's wider on the lens head itself. And it's gonna require a 3/4 inch diameter cutout hole in your trailer frame. And it does feature a PC rated light feature, meaning it's 180 degree arc of red light, so you can indicate it and see it from the side, front on or different angles. So it's a very nice polycarbonate housing, UV resistant lens. Let's go ahead and put the overhead lights back on.

Now these are rated for over 100,000 hours of runtime operation, because again, they're LEDs and they are 12 volts obviously. And again, you simply drill your hole, wire this through, and then once you get it in place, you'll push that down to the grommet. It is a tight fit, it's supposed to be a tight fit. That way whenever you get everything in place, it's not gonna pop out on you, you're not gonna lose it. And so that's basically kind of what it looks like whenever it's installed and pushed all the way in. So great option for you. This again is the mini clearance or side marker light. I'm Steven with etrailer. Reach out if you have any questions about this product or anything else that we carry, and have a great day.

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.

When I first installed it, it seemed to be dull but it was because I didn’t have a good ground.

The RV clearance light are much better than original ones. They are brighter and set closer to the surface. I replaced 2, 1 red and 1 amber and they fit perfectly. Wire color code was different, but just touch wires together and if it lights connect it.
