So idk if anyone has had or has the same problem or if anyone has any idea what it could be, but for some reason all my lighting on the right side fails after some time. I have HID fogs and head lights and after a couple months the right side just stops working both headlights and fogs. Then i have the aftermarket LED tails lights and the right blinker doesn't work either. Not to mention i have a sub and amp, and my amp has an LED on it that rarely works but at random it comes on and off same with the LED on my bass controller.

Any ideas what it could be??? Any ideas or thoughts would be helpful! Thanks!!
