So I ran into a snag tonight. My new ebay H4 headlights aren't a straight swap The rear extensions on the headlights won't pass through the centre of the headlight buckets, so I've started flaring the shelf out with a pair of pliers as opposed to grinding/cutting them out. First one done and it's a snug fit. Now for the retaining/trim ring. The "feet" in the corners of the headlights are a little too protrusive so I'll have to take maybe, 2mm off them to get the trim ring to seat properly. I was hopeful these headlights came with T10 wedge parking lights but no luck on that. I am considering blowing some holes in the casings and DIYing them. They were considerably cheap so I am not gonna complain about what I have to do to get them to mount up. I'm still waiting on the 4 ceramic socket harness to make it all operational. Then I have to integrate the lot into my new relay/fuse block. Man I do love wiring
