Having trouble finding your Mustang’s pesky light bulb number? Sometimes it's not listed on the bulb itself and your owner's manual is long gone. Don't fret! This guide will help you determine what type of bulb you're missing and where you can find a replacement or upgrade.

Replace the worn and dull backup lights on your classic Mustang with new chrome housings and clear lenses. We'll show you how to upgrade to LED bulbs, too.
