 The 9011 lamps are a direct replacement for vehicles and trucks which were designed for this type. Additionally, this bulb can replace the 9005 and HB3 for special service applications. Please see our "How-to & Tech Library" here, or by navigating to the section in the upper left hand side of this website. This 65-watt bulb is US DOT compliant and ECE type-approved. Application notes This bulb is physically, electrically, optically, and legally compatible with all other 9011 (HIR1) bulbs, so it can be used for all the same design-specification, replacement, and upgrade applications. It can replace the 9005 (HB3) for special-service use; such a retrofit requires minor modification to the bulb base as described here. |
