Mk1 Gs Sport Headlight Adjustment

samurai69 · January 24, 2011

i have been told the headlights are low on my mk 1 gs300 sport, how do i go about adjusting them up a little

on the top of the unit looks to be a small screw that may be what i need, but one of the mounting bolts has a 20 degree mark on it

also how do i change sidelight bulb........do i need to take headlight unit out

i have tried searches on here, but found nothing so far

cheers for the help

Does the thumbwheel on the dash for the headlamp height adjustment not work to raise them a bit? If not, there are two adjustment screws/bolts, for adjustment left and right, and up and down. They have a philips type cross slot in the top, plus they have a hexagonal head on to fit a spanner/socket. One of them is a tad awkward to get to. If you park facing a wall or garage door (not too close as the change won't be so obvious), you will see the beam move as you adjust it.

You need to remove the indicator to get the side light bulb out. There is a single philips screw on the top outside end of the headlamp, once removed, the indicator unit pulls out the front. You can then get to the side light bulb holder, which is a long grey rubber holder, which has to be twisted to release and pull out the back of the light.

just had another look

at the back of the lamp unit there is 1 small screw with a bolt head as you describe.......is that the adjuster for the dipped beam

as for the side light, theres one screw that holds indicator in close to the top of the headlamp, there seems to be a bolt set back in to the bulkhead close to Battery is that the other bolt for the indicator

thanks again

There is only one screw for the indicator.

I'm working off the top of my head on the headlamps as I don't have a mk1 anymore. But from what I remember, there should be one bolt visble from the top, and one tucked down the back (there maybe 4 altogether, 2 for dipped beam, 2 for main beam, but again, not entirely sure). If all else fails, park 20 feet away from a wall, stick your dip and main beams on, and have a twiddle, you should see the beams moving. If it moves left or right, but turn the adjustor back to where you started from and try one of the others. I'm sure the vertical adjustment is the one on the top, and left and right is down the back of the unit.
