Have you ever tried to adjust your headlights and found the screws (particularly the top one) are almost impossible to turn due to their age and angle you need on the screwdriver? If they are a bit stuck the screw heads inevitably get damaged. Also the springs are usually a bit on the rusty side by now.
How about replacing the old screws and springs with some nice new ones?
This kit consists of six stainless steel socket head cap screws (the heads fit through the holes in the headlight surround), stainless steel washers and new springs. The cap screws allow you to adjust the headlights easily with a ball end allen key so you don't have to worry about destroying the original phillips head screws.
If you don't have a set of ball ended allen keys, how about getting the kit that includes an allen key?
