Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

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!


Perfect fit for my hitch pod. Looks great also


Like some other reviewers, I easily installed this as a replacement light on a Thule transporter. So far, so good!


Parts arrived quickly & worked perfectly for our Thule transport cargo box.


Great product and fits my Thule transport carrier perfectly


Lights are great, shipping was quick.


Good bright replacement part!


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.


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.


They fit my Thule hitch mounted cargo box perfectly. Hoping the LED lights will last longer than the original Thule ones.


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.


Haven't installed the parts ordered yet but the shipment was correct and on time. good customer service. Will use again if I need hard to find parts.


Great replacement/upgrade for my 2003 Continental Cargo trailer.


Recieved my order a day sooner than I thought and everything was what I thought was! I highly recomend etrailer!!!


As advertised. Sure are bright !! A great upgrade from incandescent bulbs.


Much brighter


product was delivered promptly-was a snap to install and fit perfectly.


Very professional



Excellent lights and look nice and bright. Fast shipment too.




Arrived on time and as described. Good service, good price.

See what our Experts say about this Optronics Trailer Lights

  • Would the Optronics Trailer Lights # STL35RB Meet IP67 Waterproof Rating
    A submersible light such as # STL35RB is sealed and waterproof. This light is not given an IP rating but if to get an IP rating of 67 something must meet NEMA code 6 then these lights would do the trick as they are sealed and waterproof.

  • Flush Mounted LED Lights for Flatbed Trailer
    Thank you for the photos; based on what you showed, you would want oval LED lights that are in the 6-1/2" x 2" range, though you would need exact dimensions to ensure the right fit. For example, # STL72RB is a red oval light that measures 6-7/16" x 2-5/16" x 1-3/4" deep while # STL70RB is another red oval light but with dimensions of 6-1/2" x 2-1/4" x 1-1/8" deep. The same will apply for your white oval lights, such as the 6-1/2" L x 2-1/8" W x 1" # BUL72CB. The other lights look to be...

  • Replacement LED Light Assembly for Thule Transporter Cargo Carrier
    It's true! We (and other customers - see review below) have found that the Micro-Flex LED Tail Light # STL35RB works great as a replacement for the stock assemblies on the Thule Transporter Combi Cargo Carrier. LEDs typically last significantly longer than standard incandescent bulbs so you really shouldn't have to worry about replacing them. I wouldn't be surprised if they outlasted the carrier itself. I have attached a short video review as well.

  • Replacement LED and Incandescent Lights for the Thule Transporter
    Yes, the LED light part # STL35RB can be used to upgrade the lights in a Thule Transporter Hitch Mounted Cargo Carrier part # TH665C. I went out to the warehouse and test fitted the LED lights inside the original grommet that comes with the Transporter part # 05253. The pigtail that comes with the Transporter part # TH05254 fits the LED lights so there will not be an issue plugging the new lights in. If you are just looking for the original incandescent replacement light, you can replace...

  • Replacement Tail Light for a Thule Terrapin or Thule Transporter Hitch Mounted Cargo Box
    The replacement tail light for the Thule Terrapin cargo box is # TH05252. This is an incandescent light. There isn't an official LED light made for it but you could potentially use # STL35RB. It measures 5-5/16 inches by 3-7/16 inches and is 2-5/16 inches deep overall. I have linked a video review of this light for you.

  • Recommendations for installing a LED Trailer Light # STL35RB on a 2002 Ranger Trail Trailer
    This Miro-Flex, Waterproof, Rectangular, LED Trailer Stop/Turn/Tail Light # STL35RB that you referenced should work well with your trailer wiring. You will need a Straight 3-Wire Pigtail # A45PB to wire it into your trailer wiring. The red wire from this harness will run to the turn signal circuit, the black is the tail signal, and the white will ground to the trailer frame on a clean metal surface to complete the circuit. You might also be interested in purchasing a Grommet for ST33...

  • Running Lamp Circuit on Thule TH665C Transporter Combi Cargo Carrier Not Working
    The taillights on the Thule # TH665C Transporter Cargo Carrier should function as brake lamps. turn signals and running lamps. It sounds like you have a problem with the running lamp circuit, as the license plate lamp is on the same circuit. I'd first test the trailer connector on the vehicle while the headlights are on. A simple circuit tester like # PTW2993 works well for this. Check the pin on the connector that's fed by the brown wire. If you're not getting power on that wire with...
