Today my headlight stopped working so I needed to repair it, but I had to remove it first. Some lights worked and some didn't and some were all scrambled. There was a problem with the "-" (the ground in other words) and with the wires and with the contacts and water, and everything

I didn't know how to do it so I started slowly. I saw the headlight was held in place by 3 bolts (or screws or whateva) but it couldn't be removed because of the bumper. On the other hand I couldn't remove the bumper because I couldn't see all the bolts. I found most of them but some were hidden. At the end I had to remove the wheel so I could remove the plastic around it (again more unscrewing) so I could see all the bolts from the bumper. I found two of them there. I didn't remove the whole bumper, I just unscrewed enough so I can pull it enough to make room for the headlight to go out. I didn't touch the right side of the car. Just left wheel, 3 bolts at the left side of the wheel, the plastic around the wheel, 2 bolts that were hidden under it on the upper left side, 3 bolts on the left side of the car under the bumper and 2 bolts above the bumper between the 2 headlights. That was enough to pull the bumper a little down and away from the car so I could take out the headlight and unplug it from the main connector.

The contacts on the main connector were dirty and almost green from oxidation and I had to clean that. I used some wd40 and sand paper. Wire number 1, the black one, was "-" and I found that the number 4 was the long light. It's fuse is in the fuse box under the hood. The short light fuse is in the car (you have the diagrams under the lid of the fuse boxes). I changed a lot of wires in the headlight and fixed a mess that electricians left behind from their "fast fixing".

I put some silicon around the headlight so it doesn't collect rain like it used to and I'm really happy now I fixed it..... because I started clueless and scored an epic win at the end

Cheers for sticking this up here mate, just put a new light in my punto and wouldn't have a clue what to do without your post

Been searching the internet for info as I have to replace my headlights with new units.
After several hours of going through endless guides on how to replace the bulbs finally stumbled on your guide.
What a godsend. cheers for the info and pictures.

its not the best design by fiat to be honest - as the Connector for the Passenger headlight is Right underneath the Non-retrun valve from the washer tank

I too had the the Green Fun on a connector - didnt affect my lights like, and only found it because i had a wiring fault....

I used a dremel on my contacts but access is poor - so grit paper ftw defo

light can be release by just nudging bumper off

When refitting the bumper slap plenty of Copper grease in the thread hole and bolts, to stop them seizing in

Thanks very much for these picture wouldn't have been able to do it otherwise.
