Aiming FIAT 500 Headlights
Simply insert a flat head screwdriver into the round white plastic part shown in picture and adjust accordingly.
The FIAT 500 headlight adjusters accept a flathead screwdriver, a phillips head screwdriver, or a 6mm hex tool. Clockwise lowers the FIAT 500 headlights and counterclockwise raises the FIAT 500 headlights.
I actually just made use of this tutorial. It was a small project long overdue. Now I don't have to drive in fear of the police. They like to give tickets for that sort of thing where I'm from (not having your headlights aiming or working properly).
