Unlike low-beam bulbs (like 9006 or H11), the 9005 sits in a housing that expects less total runtime. When you replace it with a high-output LED or HID, you\u2019re asking the bulb to perform under sustained high heat while maintaining a precise focal point. Most generic bulbs fail here because they ignore the fundamental optical geometry of the 9005 reflector.<\/p>\n
