If you’re done with dim or short-lived bulbs, this Miro-Flex Thinline light is a solid upgrade. It uses 4 red LEDs under a red lens to put out bright, even light while drawing just 0.051 amps at 12.8V. LEDs last about 50 times longer than old incandescent bulbs and don’t have fragile filaments to break. You get clear visibility and low power use without ever having to replace a bulb again.
Moisture is the enemy of trailer lights, but this one’s built to take it. The housing and lens are sonically sealed into a single waterproof unit that keeps water out completely, even when submerged. That means no leaks, no corrosion, and no loss of brightness when your trailer hits rain, puddles, or the boat ramp.
This light doesn’t just shine—it looks good doing it. The Miro-Flex faceted reflector boosts light output while giving the lens a clean, modern style. The reflected facets spread the illumination evenly so the light stays visible and crisp from straight on. It’s a sleek upgrade that blends form and function in one low-profile package.
When space is limited, the Thinline series fits where others can’t. Measuring only 4-1/16" long x 1-1/4" tall x 1-1/8" thick, it mounts neatly on standard 3" centers without sticking out or catching on anything. It surface mounts with a bracket (A65B - sold separately) and accepts either a 1-prong or 2-prong plug for wiring flexibility.
This light meets DOT requirements and carries a P2 rating for its beam pattern—producing a controlled 45-degree spread to either side of center for dependable clearance or side marker lighting. It’s built for consistent performance that keeps your trailer safely visible on the road night after night.

Ratings & Reviews
One of the original marker lights on my trailer was partially burned out. I purchased two of these, one to replace the bad one, and one to carry for a spare. It was an exact replacement and fit perfectly.
Great customer service & the items shipped fast and were exactly what I ordered.
Will definitely order from Etrailer again... Lights work great... The only thing is that the description does not state the light base must be ordered separately..
Exact replacement for OEM lights on my trailer. Installment snap-in very easy and lights performing as specified. Very happy with lights after 6 months oHu
f operation. Would recommend.
Great product at a great price. My trailer looks amazing at night all lit up.
It appears that this will be an excellent light after I receive all of the additional parts to actually install the lights. I ordered 14 of these lights only to find out after receipt they require the mounting brackets and plug in. Thus delaying the project and incurring freight cost because the order is under the threshold for free shipping. I upgraded the freight to ground only to find out that etrailer didn't have the part of my additional parts in stock. Jury still out on this project.
Perfect replacement for my 2004 OEM lights. I converted the in closed trailer to LED. It’s been around a year and everything is just fine. Remember, quality first price second. [base plate A65PB, LED yellow AL91AB, LED red AL91RB]
I replaced all of the lights on my trailer with LED lights. I wanted to be very visible at night for safety reasons, etrailer helped me out with this. I put a dab of die-electric grease on the contacts as I did this. My trailer is extremely visible at night, now.
This was a Perfect replacement for the marker light on the left side of my Trailer!
Easy to install and simple to wire!
The light is of excellent quality and was easy to install. Customer service and receipt of the product was exceptional. I would Highly recommend etrailer.

The light has continued to perform as advertised. It was easy to install and the light is brilliant.
I almost gave this a 5 star because it is well built, easy to install and works great, but the design has flaw, at least for my application. It's so tall or thick that it is constantly getting kick off the fixture when I'm stepping up or down on the trailer. The rear side marker light, which is not near a step, keeps getting knocked off by presumably by rocks or other road debris.
These LED Miro-Flex lights are a proper upgrade. They really look SHARP! My truck is grey, my trailer is grey, I replaced all the marker and tail lights on my 09' 7x14 tandem HaulMark with these and now have better visibility during the day. After a year i still am very happy. I noticed the lights are directional, so if your at the side during the day you have to look at them straight on to see if they are working but thats really not an issue. You have markers on all four sides just for that reason as well as reflectors. I have actually gotten unsolicited compliments from other contractors on the trailer since i got these.
Just what was needed, fit perfectly
Great light. Just don't understand why they cost two more dollars than the amber ones.
I’m really glad I chose this product quick delivery easy installation definitely worth the money very bright
Great job.
Not Happy, I want the socket its supposed to be plugged into. I bought this thinking it was a kit.
Spare purchased. Part is a perfect fit for a marker light on my travel trailer.
Exactly what I needed.
easily applied to mounting attachment nice and bright, great product.
Awesome rear marker lights, very bright and visible from side angle as well. I used them on the rear sides as well.
Exact match for oem light fixture. Easy plug and play and works as advertised.
Took great and were a perfect fit. Replaced all the marker lights on my 1998 Alaskan with these. Don’t forget the mounting bracket.
Match perfect
This light is an exact replacement for a malfunctioning light on my Travel Trailer. The install was quick and easy. Lastly, the light is functioning perfectly after a full camping season last year and outdoor storage through a Michigan winter.
