Thinking I would like to upgrade my headlights rather foolishly I fitted 100 w. H4's. Result blown fuse, melted connection to one headlamp, and now headlamps worked in dim mode and full beam only. So I've removed the dim dip module, thinking this could be the cause; reconnected the wiring loom2 x blue/white joined; black /black Yellow joined, but I still have the same problem, any one have any sensible suggestions, now I've stopped kicking myself!
