Lights Headlight Aiming The headlights were properly aimed when your car was new. If you regularly carry heavy items in the trunk, readjustment may be required. Adjustment of the headlights should be performed by a Honda technician or other qualified mechanic. Replacing a Headlight Bulb 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 car to your dealer to have it replaced. Halogen bulbs are used for the high beam headlight bulbs. When replacing a high beam headlight 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. 198 Maintenance
