I also have a ZB RSV and the headlights are pretty terrible.
It was an ex GMH “demonstrator/executive driven” and I’d be pretty confident in saying the car was probably never driven at night on country roads, or someone would have done something about it!
Whilst the low beam is very average to poor, the aiming of the high beam has each light aiming off into the trees on the sides of the road, and not illuminating the road ahead.
The only thing The high beam does is light up the possums and annoy the flying wildlife.
I’ve seen the photos that were previously posted, and agree that possibly one or more of the indicated screws adjust something, but I would prefer to know the exact use of these screws before I go fooling around with them.
So far three dealerships Have indicated they didn’t know what the screws did, couldn’t look them up in any dealer manuals or guides To tell if they were actually headlight adjustment screws, yet one was happy to charge me $70-80 If I was to agree to let them adjust the headlights!!!
I have trolled overseas forums and other posts, hoping to get an insight via the Opel Insignia brand, but with no luck.
Someone, somewhere, must have some idea of adjusting the ZB commodore headlights, as panelbeaters would need to do so after front end damage.
Any help Or advice would Be Appreciated.
TIA, wayne
