The Miro-Flex LED Trailer Side Marker Light and Mid-Ship Turn Signal uses 16 LEDs to put out a bright amber light that draws very little power. At 12.8 volts, it only pulls 0.074 amps for the side marker and 0.248 amps for the turn signal. The faceted Miro-Flex reflector design spreads that light evenly and gives it a sharp, modern look. With no bulbs to replace and no fragile filaments, the LEDs last up to 50 times longer than incandescent lights.
If your trailer sees rain or gets launched at the ramp, this light is ready for it. The housing and polycarbonate lens are sonically sealed into one solid piece, so water can’t leak in and wreck the circuit board. It’s fully submersible and stays reliable through wet roads, washes, or dips into the water.
Wiring this light is straightforward. It uses a 3-wire pigtail with 20-gauge wires—white for ground, black for running light, and red for stop or turn. That setup gives you two light levels: a low intensity for running lights and a brighter one for turn or brake signals. It works on trailers that have separate circuits or can be adapted with a converter if needed.
Measuring 6" long x 2-1/4" tall x 1-3/8" deep, this rectangular light mounts flush to flat surfaces using holes spaced 4-13/16" apart. There’s no base required; you just provide your own mounting hardware. The amber lens looks sharp while keeping visibility high from the side or mid-ship position.
With its P2 rating, the beam shines out at a 45-degree angle from centerline for clear forward visibility as a side marker or clearance light. It’s bright enough to catch attention yet controlled so it meets proper lighting coverage on trailers that need a mid-ship turn signal or marker light in one unit.

easy replacement but not as bright as I expected.
I really like these LED Lights. Very bright with crisp light patterns.
Perfect replacement light for my applic ation.
Was very satisfied with shipping and pr oduct
Exactly what I was looking for. Fast sh ipping!
These are the FINEST QUALITY markers I've ever seen. I've replaced many on 3 RVs and nothing touches these for quality even at much higher price!!!! Where are the red ones????? The discription measurements are incorrect though, my ruler measures overall 5 5/8", not 6", which is actually better for my install. The website filter has them incorrectly at 7".
Very happy with this product I purchased these to replace some of the lights on my trailer and they work wonderful. very pleased with this purchase. Would recommend and purchase again in the future.
I've used etrailer on numerous times and generally avoid these reviews, but they are a very solid good helpful organization to deal with. This is a small order compared to 3 years of past orders. Save yourself some time and trouble and just buy from them. You'll be pleased at the service.
Light was exactly as described. Working great a year later. As usual, dealing with etrailer was a breeze.
Works just like I wanted. Marker light and turn signal for the front of our RV which had no side turn signals when we bought it. Looks good too.
I am using this light as a side clearance and turn indicator. The LEDs are bright enough in day light to be seen clearly. I recommend this light highly.
You guys are great. You are current with modern technology. The tail lights are L.E.D. and waterproof. I didn't have to wait long and here came the packages. That was very quick and efficient! I like the way that you can look up the exact year and make. I am impressed, etrailer! Sincerely, GARY NUTT. THX AGAIN
Second time ordering from you guys. I paid overnight shipping to ALASKA @ 2pm AK time and received my part at 10am the next day! Super rare for that to happen in AK. Thanks
From the web site they look like what I wanted. When you trailer gets here I will be putting them on.
Needed a side/turn signal on my 5th wheel RV. I installed this light and it works great.
INSTALLED ON 18 YEAR OLD BOAT TRAILER. MAKES FOR A VERY BRIGHT MID-SHIP CLEARANCE AND TURNSIGNAL LIGHT. THE BIGGEST CHALLENGE WAS WHERE TO LOCATE AND WIRE ROUTING.
I order 2 LED side marker lights, 2 chrome bezels and a utility light for my RV. I received the items within 4 days of placing my order and am very happy with the items so far. I have not yet tried to install the items but I am certain they will go together as planned. Everyone at etrailer was professional and communicated well at each step of the order and delivery process. I will recommend eTrailer to all my RV friends if they ever need parts. Thanks to everyone for making this a good experience.
I put these on the side of a 39 foot travel trailer mostly for the people next to me while towing. They are bright and useful. I do not care for the fact that they light up when the brakes are applied. Other than that they are all good.
I added these to the midship of my travel trailer for safety reasons. Being under 30 feet, they are not required. Installation went fine. Only thing, I wish from a 45 degree angle, the light would be more noticeable. But they do the job of flashing when I put on my turn signal and can be seen from the side.
Etrailer MCL48ab light from Optronics is AWESOME. Comes in AMBER and RED. 16 BRIGHT LED's along with the Miro Flex Technology. (each LED is surrounded in a highly reflective metallic prism) Like todays bright car headlights. 4 bulbs facing forward, 6 shining to the sides, and 6 shining upwards and down. Purchased amber for the trailer to see how bright this was, no getting ready to order 12 for the rear of the trailer. Was going to use Double Bullseye units, now going to use the MCL48AB. Note: there is a different part number if you reference it on the Optronics website. When you come to ETRAILER.COM to purchase it, its the same unit. Great purchase for the money, COOL look to it, solid construction, BRIGHT, great technology. The shipment from Etrailer came quickly and packed properly.
Exact replacement I was looking for
Not flush mount as described. Lens has a gap at the top which will allow rain access to the backside of the light. No mounting hardware (screws, etc) of any kind included. No installation manual or product info sheet included, so it's anybody's guess what wire runs what function. Let's hope the performance doesn't match the initial failure.

I wanted to give you more information on the light. The LED board is sealed so that water will not be able to enter inside the light. It does have a lifetime warranty on the LEDs so if they go out the light will be replaced by the manufacturer. Typically, hardware nor instructions are included, however I can tell you that thew white wire is the ground, the red wire is stop and turn, and the black wire is the running light circuit.
I use them as a mid-ship turn signal on my motorhome and they are not as bright as I was hoping for. Eventually I will switch them to a real truck side light, but for now it's okay.

About the same. Still not thrilled about the brightness but I havent switched them yet.
works well
These lights are great! Since installing them, I am amazed how much respect my rig gets. Other motorists used to give me space when I used by turn signals. Now they immediately yield to me and give me the space I need. I am so grateful that I invested in these lights!!!

I installed them on my trailer cause I felt that I needed to a turn signal on side of my 38 ft trailer. I like them very much.
