Recommended 3-Prong 3-Wire Pigtail for a Optronics Trailer Tail Light  

Updated 12/08/2025 | Published 12/06/2025

Question:

Good evening, I am inquiring if there is a 3 prong 3 wire plug for this brake light STL29RB that I could solder and then plug into a existing wire harness for a trailer. Thanks.

Yes, there is Jeff. We actually have three different 3 prong 3 wire plug pigtails that work with the Miro-Flex LED Trailer Tail Light item # STL29RB, you were looking at.

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

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

Replacement Pigtail - 3-Wire - 90 Degree item # 40-00-004

I attached a couple of pictures below so you can see the 3-prong patterns on these pigtails.

What kind of trailer do you have?

You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them.

Thank you for getting back to me. I’m actually looking for a female end if possible.

@Jeff You're welcome! Sorry, I do not have a 3-wire pigtail with female inputs.
