Headlamp; Headlamp Alignment - Aston Martin DB 9 2013 Manual

Headlamp

Warning: High Intensity Discharge (HID) bulbs produce a
very high voltage. They should only be serviced by an Aston
Martin Dealership.
High Intensity Discharge (HID) bulbs are used for the combined main
and dipped beam. HID systems produce a brilliant white light by
establishing a high voltage electrical arc between two electrodes
within a sealed glass tube. Once the arc is established, the voltage
lowers to normal operating conditions.
HID bulbs are not renewable.
Contact to your Aston Martin Dealer if a HID bulb fails to operate.
Headlamp Units: Condensation: The headlamp units will
generate condensation under certain conditions. However, this
should clear after approximately 10 minutes after the headlamps
have been set to ON.

Headlamp Alignment

Headlamp vertical aim check
and adjustment must be
completed with the vehicle
parked on a flat surface with
the headlamps facing a
vertical wall at a distance of
25 ft to the outboard internal
lens (A), with no additional
loads in the vehicle.
How to Check
Set the dipped beam to ON. Measure the height of the left side of the
beam pattern projected onto the wall. This should measure 24.80 in
(B) in from the ground for a correctly aimed lamp. This must be
completed for both right and left headlamps.
