how to replace acura 03 cl low beam headlight?

Unplug the wiring harness, remove any trim around light, and unscrew the two screws holding it in. Those same two screws are what adjust the direction the light shines on the road way.This procedure should take less than 30 minutes.

if its just the bulb you want to replace it comes out from behind the headlamp assembly. just open the hood and look down at the back of the headlamp. you'll see the connector for the bulb. remove the connector by pushing back on the lock tab at the top then push it down to remove the connector from the bulb. with the connector removed, turn the headlamp bulb about 1/4 turn counter-clockwise. it should just pull out after the tabs unlock.as a note, may parts stores and dealers will replace the bulb for you at no charge if you buy it from them because its that easy to do.hope that answers your question
