Frequently Asked Questions
How do I know if my tail light is out?
Have someone stand behind the vehicle while you turn on the headlights. You can also check the reflection in a garage wall or window.
Can a rear-end collision cause this?
Yes. Even a minor rear-end impact can crack the tail light housing, damage the socket, or break wiring connections to the tail light.
Should I replace the entire tail light assembly?
If the housing is cracked or has moisture inside, replacing the entire assembly is recommended. If only the bulb or socket is bad, individual replacement is sufficient.
