I just wanted to confirm whether or not this came as a pair of tail lights prior to ordering. Thanks

Hey Maina. The Miro-Flex LED Tailer Light w/ Reflector item # STL35RB is sold individually. This is a sealed LED light that is submersible and provides brake, tail, and turn signals. It measures 5-5/16" long by 3-7/16" tall. It has 14 diodes built into it so it's going to be quite a bit brighter than an incandescent light and last at least 25 times as longer.

You can use the following parts to get it installed you'll need one for each light as they are sold individually as well:

Grommet for ST33 Series Tall Rectangle Flush Mount Trailer Lights item # A33GB

Right Angle 3-Wire Pigtail for Optronics Trailer Lights - 3-Prong PL-3 Plug - 10" Lead item # A47PB
or
3-Wire Pigtail for Optronics Trailer Lights - 3-Prong PL-3 Plug - 10" Lead item # A45PB

Which wiring harness you pick up is going to depend on how much space you have behind your light.

What kind of trailer do you have?

Thanks Jerred! I have the THULE Transporter Combi Cargo Carrier. I got the box second hand and the lights have never worked. I recently bought your circuit tester (#PTW2993), but have not yet tested the pins, wires, or fuses. In my brief research it looks like all of the parts you recommended should work for the Transporter, assuming that the issue is the cargo box itself. Do you agree?

@MainaP You're welcome! Yes, I definitely agree! The Miro-Flex LED Tailer Light w/ Reflector item # STL35RB has been used to replace the lights on the Thule Transporter for a few years now since the original incandescent lights stopped being offered by Thule. The Right Angle 3-Wire Pigtail for Optronics Trailer Lights item # A47PB or item # A45PB will get you set up with new harnesses as well. Since you already purchased the item # PTW2993 tester, I recommend plugging the connector into your car and checking to see if there's voltage being sent through the wiring harness from you vehicle.
