9004 vs 9007 LED Headlight Bulbs: Fitment Guide for Wholesale Buyers

For North American auto aftermarket distributors, 9004 and 9007 are common dual-filament, high/low integrated headlight bulbs widely used on older pickup trucks, SUVs and classic passenger vehicles. Many buyers easily mix these two models up, which will cause fitment returns and customer complaints.

Core Difference Between 9004 and 9007

Both bulbs share similar PX29t base and 12V dual beam structure, but they differ in pin layout and beam orientation. They cannot cross-install directly:

1. 9004 (HB1)：Mostly fitted on older Dodge, Mitsubishi, Jeep and early model pickup trucks.

2. 9007：Larger market demand, popular in Ford, GMC, Ram, Hummer and many American SUV & pickup models.

Even though the physical base looks almost identical, the pin position determines high beam and low beam alignment. Wrong selection leads to reversed high/low beam, poor light cutoff and heavy glare to oncoming drivers.

Wholesale Sourcing Checklist

1. Confirm vehicle year, make and model before order placement. Never judge bulb type only by appearance.

2. Check CANbus requirement: many American older trucks have sensitive onboard systems, choose built-in CANbus decoder version to avoid dashboard warning lights and flickering.

3. Beam pattern test before bulk shipment: good LED replacement must keep sharp cutoff line, reduce glare and meet US aftermarket lighting requirement.

4. Sample testing is strongly recommended, especially if you are new to selling 9004 /9007 bulb models.
