if the fuse in the boot isnt blow check the fuses in the engine bay - its a black box on the left. When one of my headlights - left one, went out i checked all fuses under dash and in boot with no success. Finally, checked the fuse box in the engine bay and found that it was blown. There's two 15amp fuses, one is for the right headlight and the other is obviosuly for the left.
