For those that missed the status on the side, I hadn't had an issue with the headlight fuse for a while which had gone a couple of times, switched it on last night for smoke to smart billowing out and a few small flames down by the headlight. Thankfully I was at a golf club and they had a CO2 extinguisher to hand and in the time it took to go and get in thankfully the flames hadn't taken hold of anything else.
This is what it has left me with and where it appears the wires have shorted but those wires were in good condition when I changed the HID dipped beam, it's seemingly the wires that go to the sidelight and main beam that have caused it...
Thankfully it appears no looms belonging the car have been damaged and it's just left a layer of soot on the underside of the clam.
