About Headlight Bulb Sizes

A burned-out headlight should be a ten-minute fix. Too often it turns into guesswork: forum threads that disagree, fit-guides that list three different bulbs, and a second trip to the parts store.

We built Headlight Bulb Sizes to give one clear answer for your exact car. Pick your year, make and model and you get the low beam, high beam and fog light bulbs, plus any differences between trims and headlight types. Today that covers 8,315 vehicles, and we add more every week.

Where the answers come from

Nearly every answer comes straight from the carmaker’s own owner’s manual, and we link to the page it came from so you can check it yourself. When a manual doesn’t list the bulb, we only publish a size if two independent sources agree, and we label it that way. If we can’t confirm a year, we don’t list it rather than guess. You can read the details in how we source our data.

How the site is funded

Some links to retailers may earn us a small commission when you buy, at no extra cost to you. That never changes which bulb we tell you your car needs: the size always comes from the manual or our sourcing rules, never from a retailer.

Help us get it right

If a bulb we list doesn’t match what came out of your car, or your vehicle is missing, pleaselet us know. Every correction gets checked against the source and fixed for everyone.
