Frequently Asked Questions

Interchangeable bulbs share the same physical base and socket design. You can use either one in a housing designed for the other. For example, H11 and H8 are interchangeable because they have the same quarter-turn bayonet mount.

You should only use bulbs that are listed as interchangeable with your specified size. Using a bulb with a different base can damage the socket, cause flickering, or produce incorrect beam patterns.

Most vehicles use different bulb types for different positions. For example, a car might use H11 for low beams and 9005 for high beams. Each position has different wattage and beam pattern requirements.
