Outer Limits 4x4 Board

My right headlight fuse keeps blowing, and then my headlight still works but is a very dull orange colour.

I keep replacing the fuse, it lasts about an hour then blows. Any reasons why this might be happening?

Thanks

because there is a short or the fuse is to small... id say its a short somewhere, and if its lasting a while b4 it blows then its prob a loose wire that occasionaly shakes onto something causeing the short...
