Hey guys I'm having trouble with my headlights and taillights continually blowing, left or right it seems to be pretty random..

Only started happening after getting my car back from Mao and Evo-R after having new heads installed, I've looked at the fuses etc and all seems to be okay?? I've replaced approx 5 headlights and 3 taillights in the past 2 months! I'm assuming it's some sort of short? but got no idea where to start looking.

Can anyone shed some light on this??

Cheers.
Matt.
