Automotive Headlight Bulbs

Check your vehicle owner’s manual or existing bulb for the required bulb type and size (e.g., H1, H4, H7, 9005, 9006); verify whether your headlight assembly uses halogen, HID, or LED to ensure compatibility and proper fit

LED bulbs may require a compatible housing, CANbus decoder, or anti-flicker adapter for some vehicles to avoid error codes and glare; confirm physical fit, beam pattern, and cooling/space requirements before purchasing

Halogen bulbs commonly last 500–1,000 hours, HID bulbs around 2,000–3,000 hours, and quality LED bulbs often last 10,000–30,000 hours, though actual life varies with build quality, driving conditions, and heat management

A correct beam pattern concentrates light on the road without blinding oncoming traffic; choose bulbs designed for your reflector or projector housing and have headlights aimed to manufacturer specifications after installation

Many jurisdictions regulate bulb color, brightness, and use of aftermarket conversions; ensure replacements meet local vehicle lighting laws and DOT/ECE markings where required to avoid safety and compliance issues

Avoid touching halogen bulbs with bare hands, ensure proper ventilation for LEDs, secure wiring and connectors, replace bulbs in pairs to maintain even illumination, and periodically clean headlight lenses to prevent light loss
