Q: Can I upgrade my halogen bulbs to LED?

Yes, most halogen bulb sizes have LED replacements available. LED bulbs are brighter, last longer, and use less power. Just match your current bulb size when ordering an LED kit.

Q: Are all bulbs with the same size number interchangeable?

Bulbs with the same size designation (e.g., H11) share the same base and fitment, so they are physically interchangeable. However, they may differ in technology (halogen, LED, HID), brightness, and color temperature.

Q: What is the difference between H11 and 9005 bulbs?

H11 and 9005 are different bulb sizes with different bases. H11 is commonly used for low beams and fog lights, while 9005 (HB3) is typically used for high beams. They are not interchangeable.
