This Underground Lighting collection focuses exclusively on 9006 headlight bulbs, also known by the SAE designation HB4, a single-beam lighting standard engineered primarily for low-beam headlights and widely used in factory fog light housings. A 9006 bulb is a single-filament light source, meaning it performs one function per bulb—most commonly low beam, and in some vehicles, fog light duty. Designed for 12V automotive electrical systems, the 9006 bulb uses a P22d right-angle twist-lock base with an integrated O-ring seal, ensuring correct polarity, moisture resistance, and consistent beam alignment.
- Bulb type: Single-beam halogen (OEM reference)
- Socket: P22d plastic base with O-ring seal
- Voltage: 12V DC
- Halogen wattage: 55W
- Halogen output: ~1000–1350 lumens
- Primary applications: Low beam headlights, fog lights
The range brings together OEM-style HID replacement bulbs, plug-and-play 9006 HID conversion kits, and CANbus-compatible 9006 LED headlight and fog light kits. Every product in this collection is built to improve forward visibility, color consistency, and electrical reliability compared to stock halogen bulbs, while maintaining compatibility with reflector and projector housings where applicable.
What This 9006 Headlight Bulbs & Kits Collection Includes
1. 9006 LED Headlight Bulbs & DRL Kits
Solid-state LED systems designed to replace halogen 9006 bulbs in low-beam and DRL applications.
- 9006 60W 12000LM CANbus LED Headlight Bulbs DRL Kit (PAIR)
- Output: up to 12,000 lumens per pair
- Color temperature: 6000K pure white
- Power draw: ~60W total system load
