Lights Replacing a Headlight Bulb Your car has two bulbs on each side, four in total. Make sure you are replacing the bulb that is burned out. Your car uses halogen headlight bulbs. When replacing a bulb, handle it by its plastic case 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. The headlight bulbs in your car are H1 headlight bulbs for longer life. We recommend the use of Genuine Honda parts for replacing a headlight bulb. HORIZONTAL ADJUSTMENT VERTICAL ADJUSTMENT 6. If either indicator is not aligned with its "0" mark as described, an adjustment can be made using a Phillips-head screwdriver to realign it with the "0" mark. Please refer to the illustrations. 7. If you cannot get an indicator to align, have your Honda dealer inspect the vehicle for body damage or suspension problems. NOTICE Halogen headlight bulbs get very hot when lit. Oil, perspiration, or a scratch on the glass can cause the bulb to overheat and shatter. Maintenance
