Headlight low and high beam bulb failure can happen over time due to the age of the bulb. It is recommended that you replace both lights at the same time for two main reasons.

NOTE: It is important that the headlight bulb fits in the headlight socket properly. If the bulb doesn’t fit properly in the socket, the light beam will not project correctly. You can verify this by turning on the light and looking at the headlights from 20 feet away. Both headlights should be the same brightness.
