Features to know about

Reliable Visibility in Any Condition: Bright Amber LED Output

This 1" diameter amber light makes sure your trailer is seen, day or night. The premium LED is energy efficient, long-lasting, and vibration resistant, so you get steady performance without worrying about burnt-out bulbs. It runs on 9V-14V DC and draws just 0.03-0.06 amps, keeping the load light on your electrical system while putting out a strong, clear signal that meets FMVSS 108 standards.

Built for the Elements: Fully Sealed and Submersible Construction

Water and dust are no match for this IP68-rated, sealed unit. The housing and lens are permanently bonded to create a single waterproof piece, so you can count on it even when your trailer gets submerged. Inside, the circuit board is protected by TecSeal urethane potting that keeps out moisture better than common epoxy potting. This means reliable operation whether you’re backing down a ramp or hauling through heavy rain.

Wide-Angle Safety Coverage: PC-Rated 180-Degree Beam

A PC rating means this light throws a consistent 180-degree spread of amber light—90 degrees to each side. Mounted properly, it serves double duty as both a clearance and side marker light, giving other drivers a clear view of your trailer’s position from the front and sides. You don’t have to double up on lights to meet safety requirements—this one does both jobs cleanly.

Simple Mounting in Tight Spaces: Compact Recessed Fit

The small round design fits neatly wherever you need extra visibility. It installs in a 3/4" diameter cutout using the included grommet for a flush, protected mount. The 9" pigtail with 0.156" barrel connectors plugs into matching connectors on your trailer for a clean, direct hookup—no rewiring or adapters needed. At just 7/8" thick, it tucks in securely without sticking out or catching on anything.

Tough Enough for the Long Haul: Durable Materials and Construction

With its automotive-grade polycarbonate lens and military-grade circuit board build, this light is made to last up to 100,000 hours of use. It’s impact resistant and UV stable, so harsh sun or rough terrain won’t wear it down. Whether used as a clearance or marker light, it delivers dependable performance trip after trip.

Video Transcript for Review of TecNiq Trailer Lights - Mini Clearance Submersible Amber LED Marker Light Grommet - TN57MR

Hi, everybody. Andy here with etrailer.com. Let's take a real quick look at this mini clearance submersible amber LED and amber lens side marker light with grommet. Now, this small, round amber LED light is going to serve as a front side marker and clearance light for your trailer. This PC-rated light is going to produce a 180-degree arc of amber light to indicate the position of your trailer. So you can see just how bright this is with my studio lights on.

Let me turn those off to give you a better idea of what this is going to look like in low light or dark conditions. I'm gonna zoom back out here just so you can see what this is going to look like from a distance. So this premium LED is energy efficient, it's long-lasting, and it's vibration resistant. Just shining that on the wall behind me. This is rated for up to 100,000 hours of operation, and this is an amber lens over an amber LED.

So let me go ahead and turn my studio lights back on. So I'm gonna go ahead and disconnect this from power. And this is going to be a one inch in diameter light and the thickness is 7/8 of an inch. And then the dimensions without the grommet, that's gonna knock down the diameter to 3/4 of an inch. And again, it's gonna be right at 7/8 of an inch thick.

So this is obviously a recessed mount installation with this included grommet and it does require a 3/4 of an inch diameter cutout. And this sealed waterproof unit includes a durable polycarbonate housing and UV resistant lens and military grade construction of the circuit board and the urethane potting is going to offer better protection than common epoxy potting. This is 12 volt DC compatible and you're gonna hook this up with the 0.156-inch barrel connectors. They're gonna plug into your trailer's matching connectors. This is going to meet or exceed the FMVSS 108 standards.

But I think that's gonna wrap up our really quick look today. I do hope that our brief time together was illuminating for you. Again, my name is Andy. Thank you for joining me.

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:
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.

a fun little project, I put new tail lights on my trailer and found out I had one bad wire , so I pulled new wires and added these onto my Roller guides , look really nice!

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.
