Yeah man been through a heap on my 33, it's even got to the point of them cutting out when i hit bumps, but cant find any issues with the wires or connections!!! i'm stumped, last time i drove it i had to use high beam the whole night cause low beam didn't work at all on either side!!!
oly thing i can think of is the clips that hold the globe in may not be connecting 100% of the time and shorting out the globes!!
just a guess though!
