on a glanza rep (with the glanza headlights fitted) i found that the adjuster inside the car wouldnt adjust the headlights. to do it manually, you have to wind in the 2 mounting points. if the are pointing towards the floor you'll have to undo them (with a ratchet) you'll find the 2 here (circled in red, and then you'll be able to see the other 2 towards the wings i have an n/a exhaust, but theres no backbox to it if thats any good?
