Product Specifications

The H4B halogen automotive bulb is a variant of the H4 series halogen bulbs.

 Compared with traditional H4 halogen bulbs, H4B bulbs usually have slightly lower power or subtle differences in design to meet certain specific automotive lighting needs. While their structure and functions are similar, H4B halogen bulbs have adjustments in specific design and performance due to different standards and application scenarios.   

 Generally, H4B bulbs share the same core design as standard H4 halogen bulbs: they adopt a dual-tungsten-filament structure, with one filament for low beam and the other for high beam. The interior of the bulb is filled with halogen gas, enabling it to provide higher brightness and a longer service life during operation.   

 H4B halogen automotive bulbs deliver high brightness and strong light penetration, which can effectively illuminate roads at a longer distance. 

Their light color is usually warm white or slightly yellow, making them suitable for nighttime driving or use in severe weather conditions (such as fog, rain, snow, etc.). Additionally, they boast good luminous efficiency, providing uniform light distribution, reducing glare, and thus enhancing driving safety.
