To get to head light front bumper have to be remove inside the headlight the wiring harness touches the housing of the headlight causes a direct short.
may not be the problem, on the bmw 750's a malfunction of a light means you might only have to change the bulb. You can go to autozone and buy a 4 dollar bulb first before you did to deep into your pocket.
take the turn signal bulb holders out and clean the terminals - mine were very dirty - now they are clean the problems have gone. total cost - 1 small piece of emery paper.
