Frequently Asked Questions

Is a side marker light the same as a turn signal?

No. Side marker lights are small amber or red lights on the fenders that remain steadily lit. Turn signals flash to indicate direction changes.

Can I drive with a side marker light out?

Yes, you can drive safely, but in many states a burned-out side marker will cause a failed safety inspection.

How hard is it to replace a side marker bulb?

It is one of the easiest automotive repairs. Most side marker bulbs can be accessed by turning the socket counterclockwise from behind the fender liner.
