Swapping out old incandescent lights for this Miro-Flex LED tail light makes an instant difference. Fourteen red LEDs glow bright for tail lights, then kick up another notch for brake and turn signals. They draw only 0.301 amps at 12.8 volts when braking or signaling and just 0.020 amps for tail lights, so they’re efficient and easy on your electrical system. Plus, the LEDs are built to last with a lifetime warranty—no more chasing bad bulbs or weak light output.
If your trailer ever hits wet roads or the boat ramp, this light is ready. The housing and lens are sonically sealed into a single waterproof unit that keeps moisture out completely. It’s submersible and corrosion-resistant thanks to its durable, all-weather polycarbonate body. Even after repeated dunkings, the LEDs stay protected and reliable, so you can tow with confidence in any conditions.
This rectangular light measures 5-5/16" long x 3-7/16" tall x 2-5/16" thick and mounts flush in a cutout using the grommet A33GB (sold separately). The standard PL-3 connector accepts either the straight pigtail A45PB or the right-angle A47PB, depending on your setup. It’s an easy retrofit for older lights that used the same style plug—just pop it into the grommet, plug it in, and you’re done.

The Miro-Flex faceted reflector design doesn’t just look sharp—it boosts light output for better visibility from all angles. The built-in reflector means no extra parts are needed for compliance or reflection on the road. It meets FMVSS 108 and CMVSS 108 standards, so you know it’s fully DOT compliant right out of the box.

Lights are great, shipping was quick.
As advertised. Sure are bright !! A great upgrade from incandescent bulbs.
Easy to order, fast shipping, easy to install…
Video was the key!
Parts arrived quickly & worked perfectly for our Thule transport cargo box.
Recieved my order a day sooner than I thought and everything was what I thought was! I highly recomend etrailer!!!
Great replacement/upgrade for my 2003 Continental Cargo trailer.
Haven't installed the parts ordered yet but the shipment was correct and on time. good customer service. Will use etrailer.com again if I need hard to find parts.
Perfect replacement for stock bulbs in Thule rear mounted cargo carrier. Super easy to replace. Order shipped same day and made it here in one day. Awesome service!
Had to force in to the rubber mount and the fixture took-a-licking and kept on ticking. Great item - ps: used on custom truck bed, not on trailer.
this item looks well made, but I was disappointed it did not include the PL 3 plug with it
Looks and works way better than the factory lights on my Thule Transporter Combi.
They fit my Thule hitch mounted cargo box perfectly. Hoping the LED lights will last longer than the original Thule ones.
My experience has been without any negative issue. Etrailer kept me informed during the entire shipping process. Delivery was ahead of schedule. I have only had the tail lights for one day. The installation was not very difficult. So far, everything is meeting my expectations. Thank you.
After dealing with Thule reps and home office it is refreshing to deal with
JB at etrailers.
I had a warranty issue with Thule, of course they have no replacement parts, thus no warranty. A great business plan no cost warranty on their end.
JB took excellent care of me, I will not hesitate to recommend etrailer to all.
I replaced boythtaillights on my combi box.
Fit perfectly On my Thule Transporter. There was no need to order anything else, it was a true plug-and-play. I went with these because a while back, one of my old lights went out and I replaced it with OEM lights, a day or so later, the other old light gave out.
I ended up buying the pair of these. I’m very happy with these so far.
I can’t give it a 5-star because I haven’t owned them long enough. Time will tell if they last.
etailer has everything, even these tail lights for my Thule hitch Terrapin Cargo Box to replace the original sealed incandescent Tail Light Units.
Perfect fit for my Thule combi carrier. Time will tell if LED are more durable. Recommended!
Fit perfectly in Thule hitch box, offers a much brighter output than the original halogen, and makes me feel better about the lights’ survival after potential submersion in water. I had to replace because a halogen light went dead. A steep on the price, but eTrailer was no different than any other place and etrailer was great, as usual. I prefer to support etrailer than [online vendor].
Looks and works great! Arrived ahead of time !
Great price, arrived quickly, fits the existing Thule Combi grommet, wiring and cutout. Very simple and easy to install.
These were a fairly easy replacement for the OEM tail lights in the Thule Transport 665. Once the liner was removed and the lights were removed from the weather gaskets, it was simple matter of switching to the LED lights - no changing wires or other MacGyver-ing needed!
Amazing lights worked perfectly plug-in play not only that but their customer service 10 out of 10 beyond happy!
I appreciate eTrailer for all things that attach to a hitch. They have been more than helpful for parts to update/repair second hand/eBay/Marketplace purchases. From RV stuff to my new hitch mounted spare & rack. Quick response from customer service!
