Question:
hi i have a hopkins trailer light kit installed on my 1992 landcruiser and Ive had a lot of issues with Mutiple trailers having very dim lighting. is there a booster module or something i could add to help? the lights come on and do all the functions, but theyre just really dim. Even on LED trailer lights.

Hey Cody,
The most common issue with trailers having dim lighting is a weak ground connection. I would double check, and even re-ground the ground wire on the vehicle and/or trailers to make sure all of the grounds have a strong connection. Since they all work there is not going to be an issue with the actual harness itself.
If you check the grounds and they are still dim let me know and I can continue to troubleshoot.

Hey Cody, how did it go with checking the ground connections on your trailer lights? I'm curious if that helped brighten them up. Let me know if you need more help troubleshooting!
