HB4 bulbs as the same as 9006 bulbs? Why they call HB4?

Yes! HB4 headlight bulbs are indeed the same as 9006 bulbs. The designation HB4 is used in the European standard for automotive bulbs, while 9006 is the designation used in the North American standard. Despite the different naming conventions, HB4 and 9006 bulbs refer to the same type of bulb with identical specifications and applications.

Here's why they are sometimes referred to as HB4:

European Standard (HB4): In Europe, automotive bulbs are designated using a combination of letters (indicating the type of bulb) and numbers (specifying the specific bulb type). HB4 specifically refers to a single filament bulb with a particular base and electrical specifications, which aligns with the 9006 bulb used in North America and other regions.

Interchangeability: Despite the different naming conventions (HB4 vs. 9006), the physical and electrical specifications of the bulbs are the same. They both operate at 12 volts and are commonly used as low beam or fog light bulbs in vehicles equipped with separate high and low beam headlights.

Functionality: Like 9006 bulbs, HB4 bulbs are known for their performance as low beam or fog light bulbs. They provide adequate visibility with a specific color temperature and brightness level suitable for these applications.

Global Recognition: Manufacturers and retailers often use both designations interchangeably to describe the same product, ensuring global recognition and compatibility across different markets.

In summary, HB4 headlight bulbs and 9006 headlight bulbs are identical in terms of specifications, functionality, and application. They are interchangeable and serve the same purpose as low beam or fog light bulbs in vehicles equipped with separate high and low beam systems, depending on regional naming conventions.
