2001 NISSAN ALTIMA headlight aiming

HEADLIGHTS
The headlamp is a semi-sealed beam type
which uses a replaceable halogen bulb.
Because the headlamp assembly must be
removed from the vehicle for bulb replace-
ment, it is recommended that your vehicle
be taken to an authorized NISSAN Dealer.
Replacing the headlight bulb
CAUTION
cDo not leave the headlamp assembly
open without a bulb installed for a
long period of time. Dust, moisture,
smoke, etc. entering the headlamp
body may affect bulb performance.
Remove the bulb from the headlamp
assembly just before a replacement
bulb is installed.
cOnly touch the plastic base when
handling the bulb. Never touch the
glass envelope. Touching the glass
could significantly affect bulb life
and/or headlamp performance.cHigh pressure halogen gas is sealed
inside the halogen bulb. The bulb
may break if the glass envelope is
scratched or the bulb is dropped.
cUse the same number and wattage
as originally installed:
Wattage 65/55
Bulb no. 9007(HB5)
cAiming is not necessary after replac-
ing the bulb. When aiming adjust-
ment is necessary, contact an autho-
rized NISSAN dealer.
