H7 & H11 LED Headlight Bulbs: Wholesale Sourcing Guide for Auto Aftermarket Distributors
For North American auto aftermarket distributors and retail modification shops, H7 and H11 are two of the most popular single-beam LED replacement bulbs. Many new buyers mix up their socket structure, beam function and vehicle compatibility when placing bulk orders.
### H7 LED Headlight Bulb
H7 is a widely used single-beam bulb, common on European sedans and many imported passenger vehicles. It only works for either high beam or low beam, which means the vehicle needs two separate bulbs for high/low beam function.
- Base type: PX26d single-tab base
- Application: Low beam or high beam for European style vehicles
- Wholesale note: H7 bulbs often require adapter retainer clips for installation. You need to confirm whether the package includes clips before bulk purchase.

### H11 LED Headlight Bulb
H11 (including H8 / H9 variants) is a single-beam bulb, mainly used for low beam and fog lights. It is extremely common on Japanese and Korean vehicles, as well as many US domestic models.
- Base type: PGJ19-2 twist-lock base
- Application: Low beam, fog lamp, daytime running light
- Wholesale note: Many H11 LED bulbs have larger cooling fans. Please check rear housing space of car lamps to avoid fitment issues.
