When converting a halogen or incandescent bulb on your vehicle to LED, it can oftentimes be difficult to determine what bulb size you need when the bulb size listed in your owner's manual or on the bulb doesn't match the sizes you find online. Many bulbs use the same base and connectors, but are referred to as a different bulb size in your owner's manual. Below you will find a list of the most common bulb bases and their cross references.
