2011 Acura MDX headlight bulb

Headlight Aiming
The headlights were properly aimed
when your vehicle was new. If you
regularly carry heavy items in the
cargo area or pull a trailer,
readjustment may be required.
Adjustments should be done by your
dealer or another qualified
technician.
Low Beam Headlight Bulb
Replacement
The low beam headlight bulbs are a
type of high voltage discharge tube.
High voltage can remain in the
circuit even with the light switch off
and the key removed. Because of
this, you should not attempt to
examine or change a low beam
headlight bulb yourself. If a low
beam headlight bulb fails, take the
vehicle to your dealer to have it
replaced.Replacing a High Beam Headlight
Bulb
Your vehicle has halogen headlight
bulbs. When replacing a bulb, handle
it by its base, and protect the glass
from contact with your skin or hard
objects. If you touch the glass, clean
it with denatured alcohol and a clean
cloth.
Halogen headlight bulbs get very hot
when lit. Oil, perspiration, or a scratch
on the glass can cause the bulb to
overheat and shatter.
