9004 headlight bulb

The 9004 headlight bulb is another type of dual-beam bulb commonly used in automotive headlights. It's similar to the 9008 (H13) bulb but differs in its design and specifications:

Dual-Beam Functionality: Like the 9008 (H13) bulb, the 9004 bulb is designed to serve as both high beam and low beam headlights in vehicles with dual-beam headlight systems.

Electrical Specifications: The 9004 bulb operates on a different electrical system compared to the 9008 (H13) bulb. Specifically, the 9004 bulb uses a different pin configuration and is wired differently from the 9008 (H13).

Physical Design: The physical design of the 9004 bulb includes a specific base and filament arrangement that differs from the 9008 (H13) bulb. This means they are not interchangeable without modifying the wiring or using adapters designed for conversion.

Brightness and Compatibility: When choosing a 9004 bulb, consider factors such as brightness (lumens), color temperature (Kelvin), and compatibility with your vehicle's make, model, and year. Ensure the bulb meets regulatory standards for automotive lighting in your region.

It's essential to verify your vehicle's specific bulb requirements before purchasing replacement bulbs to ensure compatibility and proper functionality. If your vehicle originally came with 9004 bulbs, replacements should also be 9004 bulbs unless you are willing to modify the wiring or use conversion kits designed for different bulb types.
