Question:

I have a popup camper that Im having a difficult time getting the turn signals to light up brightly enough. Was wondering if you have any suggestions before I spend $240 having a professional repair it.

Since I'm assuming you just installed the # V457 and # V457L it is unlikely the lights themselves are the problem. It could have to do with the installation. These lights are designed to ground through the mounting hardware. Make sure the hardware is running into a metal surface that contacts the trailer frame. You could also run a separate ground wire to the frame or main ground wire if it seems like that is the problem.

The only other thing it would be is the power running to the lights. You can use a circuit tester like # PTW2993 to make sure they're getting 12V power. If not, you may have a short or the main ground for the wiring harness could be bad. Work your way back and repair as needed.
