the headlight adjustment screw? I could've sworn I saw someone here mention it before but after an hour of searching, no luck.

 

An allen wrench

 

You know what size?

 

Nope, but you can pick up an allen multi-tool fairly inexpensively at any hardware store and they do come in handy.

 

I believe you can also use a phillips screwdriver. mine has the option for both.

 

DANGER carwatcher , proceed with caution , the adjuster mechanism inside the headlight is made of white dog poo , it will crumble at the first sign of pressure , I find a squirt of lube helps but if it locks up DON'T FORCE IT , that said , allen key or philips should be fine .

Cheers ,

Mike.
