What’s the Difference Between 9005 and HB3 bulbs

The difference between 9005 and HB3 bulbs mainly lies in their naming conventions and geographical usage. Here’s a breakdown:

Naming Conventions:

  • 9005: This is the designation commonly used in the United States.
  • HB3: This is the designation used in Europe and other parts of the world.

The automotive industry has developed differently in various parts of the world, leading to regional naming conventions and standards. The US and Europe developed their own systems for categorizing and naming automotive parts, including headlight bulbs.


  • 9005: Often referred to by this name in the American automotive market.
  • HB3: Recognized under this name in Europe and in international standards.

To bridge these regional differences, organizations like the United Nations have worked on creating universal standards. Despite these efforts, the legacy names (9005 in the US and HB3 in Europe) have persisted in their respective markets.


The United Nations established universal standards to ensure consistency in bulb classification across different regions. Under UN Regulation 37, HB3 is classified in Group 1, indicating it’s approved for use as a headlight bulb. Meanwhile, 9005 serves as the corresponding US trade number. Over time, different regions have developed preferences for specific terms and standards, leading to the continued use of both 9005 and HB3 designations.

Equivalent to HB3 and 9005

The 9005 and HB3 bulbs have a few equivalents, though their full equivalence can vary based on certain factors. Here’s a look at the equivalents and their level of interchangeability. The HB3 and 9005 bulbs are equivalent, along with several other bulb sizes: H10, 9040, 9055, 9140, 9145, 9150, and 9155.

H10 Bulbs:

The H10 bulb is often considered equivalent to the 9005/HB3 bulb. Both have similar bases and can fit into the same socket, but there might be differences in wattage and light output.


The 9005XS is a variant of the 9005 bulb. The "XS" indicates a straight base, making it suitable for different mounting situations compared to the standard 9005, which has a right-angle base.

While the bases may be similar, the wattage and voltage of equivalent bulbs can differ. For instance, H10 bulbs typically have a lower wattage compared to 9005 bulbs. This can affect the brightness and heat output. The beam pattern can vary slightly between different bulbs even if they fit the same socket. This affects how light is distributed on the road, which can be important for visibility and safety.

Even if a bulb is considered an equivalent, it’s crucial to check the vehicle manufacturer’s specifications to ensure compatibility. Some vehicles may have unique requirements for heat dissipation, electrical connections, or housing space.
