What Is a 9006/HB4 Headlight Bulb?

The 9006 headlight bulb (HB4) is a single-beam bulb most commonly used for low beams and fog lights. Compared to halogen or HID, Lasfit’s 9006 LEDs provide higher brightness, whiter color, instant light-up, and longer service life—while drawing less power.

Both 9006 and 9005 are popular upgrade paths, but they serve different roles and use different bases. They are not interchangeable without modification.

  • 9006 / HB4: Typically low beam or fog light; right-angled connector, lower nominal wattage.
  • 9005 / HB3: Typically high beam or DRL; straight-keyed base, higher output.
Beam Pattern 9005 vs. 9006

Always confirm fitment for your exact year/make/model and application (low beam, fog, DRL, high beam).

Frequently Asked Questions

FAQs About 9006 LED Bulbs

1. Are 9006 LED bulbs worth it? Why upgrade?

Yes! Upgrading to 9006 LED bulbs offers significant benefits: 300% Brighter Light: See farther and wider with improved visibility. Longer Lifespan: Last up to 30,000 hours—outliving halogen bulbs. Energy Efficiency: Draw less power while producing more light. Modern White Light: Reduce eye strain with crisp, daylight-like illumination.

2. Are 9006 headlamp bulbs high beam or low beam?

9006 headlamp bulbs are primarily designed for low beams and fog lights. Using them for high beams is uncommon and not recommended, as their beam pattern is optimized for wide, short-range illumination rather than long-distance projection. Always check your vehicle’s manual to confirm bulb applications.

3. Can I install 9006 LED light bulbs myself?

Absolutely! Most 9006 LED light bulb installations are plug-and-play and can be completed in under 30 minutes with basic tools. No wiring modifications are needed—just align the bulb base correctly and secure it in the housing.

4. How do I know if 9006 LED lights will fit my car?

Compatibility is easy to check: Use our Bulb Finder tool (enter your vehicle’s year, make, and model). Check your owner’s manual for bulb size specifications. Confirm the bulb’s application (low beam/fog light). Pro Tip: 9006 and HB4 are the same bulb—just different naming conventions.

5. Can 9006 LED bulbs be used for fog lights?

Yes! 9006 LEDs are an excellent choice for fog lights. Their wide, low-reaching beam pattern cuts through fog, rain, and snow effectively, enhancing safety in adverse weather conditions.

6. Do 9006 LED bulbs work in extreme weather?

Definitely. LASFIT 9006 LED bulbs are IP67-rated, meaning they’re sealed against dust, moisture, and temperature extremes. They perform reliably in rain, snow, and heat without flickering or dimming.

7. How long do LED 9006 bulbs last?

With an average lifespan of 30,000+ hours, LASFIT 9006 LEDs far outperform halogen bulbs (which last ~1,000 hours). You’ll enjoy years of reliable use with minimal maintenance.

8. What’s the difference between 9005 and 9006 bulbs?

While they look similar, 9005 bulbs are designed for high beams, with higher light output and a focused beam. 9006 bulbs are for low beams and fog lights, with a wider, shorter beam pattern. They are not interchangeable due to different base designs.
