Why 9005 and H11 Are Not Interchangeable

The 9005 and H11 have different base designs and are not physically interchangeable. Attempting to force one into the other's socket can damage the housing or create a loose connection that causes flickering or overheating. If your vehicle uses both bulb types in different positions, make sure you purchase the correct size for each position. Always verify the specific bulb type stamped on the existing bulb or listed in your owner's manual before ordering replacements.
