So i've added foot light to my car after getting the car... 2 weeks ago.. my foot light + dome light kept turning on and off while i was driving.. sometimes it turns on when i drive thru speed bumps (@ low speed) n some times when i accelerate... n some times when i brake.. pls help me!! it is very annoying cuz i have to turn off my dome light cuz it keeps on going on n off!

all i did to the mod is extending my dome light wires which are attached to the fuse box under the steering wheel and hooked up the foot light LEDs.. n also changed the dome light to LED.. i dun think the mods i did caused the problem.. since the lights only turn on when i open the doors.. it should be the sensors problems... i want to take it back to the dealership to help me check it.. but since i modified the fuse box.. does it void the warantee? n wht do u guys think the problem is?

thx guys
