This Miro-Flex LED tail light packs 18 diodes into its 5-1/4" x 5" square housing, giving you strong, even illumination for stop, tail, and turn functions. The faceted Miro-Flex lens design increases visibility and adds a clean, modern look. At 12.8V, the stop and turn functions draw only 0.174 amps while the side marker uses just 0.054 amps—so you get bright light output with minimal power draw and none of the heat or fragility that comes with incandescent bulbs.
No more worrying about dunking your trailer lights at the ramp or driving through rain. The light’s sealed, waterproof housing keeps moisture out completely, making it safe for full submersion. The internal circuit board is protected from corrosion or shorting, so the LEDs stay bright and reliable even after repeated water exposure.
This single unit handles six essential lighting functions—stop, tail, turn signal, side marker, side reflex reflector, and rear reflex reflector—so you don’t need multiple fixtures to stay legal and visible. It’s DOT compliant and meets FMVSS 108 standards in any 360-degree mounting position, giving you full flexibility while maintaining proper visibility on the road or at the dock.
Durability starts with molded plastic housing and surface-mount LED construction that stands up to vibration and heat better than traditional bulbs. The stainless steel mounting hardware slides along rear channels so you can fine-tune placement for an exact fit. Mounting studs are spaced 2" apart on center, making installation straightforward whether you’re replacing old lights or outfitting a new setup.
Wiring is simple thanks to a color-coded 3-wire pigtail—white for ground, brown for tail light, and green for stop/turn. It even includes twist-on wire connectors to make setup quick. Once wired in, you can count on the LEDs’ long lifespan and lifetime warranty to keep your trailer safely lit season after season.

Great light. Very bright. Glad I could get a single side replacement for one that was damaged on trailer.
Great replacement light. Installation is easy. I bought this to replace the passenger side I caught on the side of my building.
HADN'T GOT THEM ON YET ,BUT ORDERED 10:00AM TUESDAY AND GOT THEM 10:30AM WEDNESDAY. GREAT SHIPPING IS ONE THING I CAN SAY ABOUT ETRAILER.WILL ORDER AGAIN IF I NEED ANY TRAILER STUFF.
Great product, works excellent! Shipping and handling fast and without any problems. Will be ordering RV TOWING parts soon.
Bought a new brake controller and updated all the lights to LEDs , all parts are good quality. Would recommend etrailer
These lights are BRIGHT and RELIABLE! I am so happy that I don't have to keep constantly checking my trailer lights to make sure they are still working.
I pull a 26 ft boat from Florida to Upstate NY every summer. I travel busy Interstates as well as country roads and always manage to find some pretty nasty weather where the visibility is very poor. The Optronic Micro-Flex tail lights give me a good feeling that the guy behind me, sees me and sees my brake lights and directionals. One of the new lights had moisture in it the first time I launched. etrailer was quick to send me a replacement under warranty, Thank You
Product was good, only issue it that e-trailer sent me a used or returned item. Everything work just fine. This light had some cog webs inside the mounting area.

Right and Left LED Brake/Turn/Tail/License plate lights
Nice bright LED light. Cheaply made, all plastic back housing but unless you can find the older (80's/90's) lights, your stuck with "made in Japan"
Well, I ordered the wrong light and best I remember I needed the one for the left side but ordered one for right side- I tried to stop order and change it but for some reason y’all wouldn’t let me do that without a whole lot of trouble.
I just used it- had to turn it upside down! Lol
Works fine just looks funny!
One year later and these LED submersible boat trailer lights are still working like the day I installed them.
Great trailer lights simple installation. Will be back here next time I need any trailer parts. Thanks
Here are pictures of the LED tail lights and marker lights that I installed after refurbish this 20' gooseneck trailer.

These lights have worked flawlessly on my boat trailer for several years down. Love them.
