Does anyone know what the second white adjuster on the back of the headlights is for? In the picture the one circled in blue is the vertical alignment but the one circled in yellow appears to do nothing on mine........
Thanks, had to have a new headlight as a pickup truck with a towbar reversed into me in a car park, only damage was a cracked headlight (amazingly they did leave their details and paid for the new light unit) - experimented with the alignment screws on the old one before I took it out so I knew which was which but that one did nothing so must have been broken. The horizontal adjuster does work on the new one as I've just put it in.
