Headlamp Alignment - Lotus 2005 Elise Owner's Handbook Manual

Headlamp Alignment

The headlamps of your Elise were correctly adjusted during
the manufacture of the car, and should only require subsequent
adjustment if the headlamp assembly or front body is disturbed.
Simply replacing the bulb will not affect alignment. Incorrectly
adjusted headlamps can cause poor lighting performance or
dazzle to oncoming traffic. Special headlamp setting equip-
ment is required to correctly set the headlamps, such that only
qualified technicians using appropriate equipment should be
entrusted with this procedure:
1. Using beam setting equipment compatible with local regu-
lations, position the machine between 300 and 700mm in
front of the LH headlamp, and parallel with the two headlamp
units using the sight bar or similar device dependent on the
machine design, to ensure cross car match. Use the guides
provided on the machine to ensure the correct height and
lateral setting.
2. Switch on the headlamp low beams (uppermost lamps) and
check the lateral beam alignment. The 'knee point' of the
beam cut off line must lie within a tolerance of 2% to the pas-
senger side, and 0%. Check the vertical alignment of the low
beam which must lie within a tolerance of -0.5% and -2%.
