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.
