Are H11 and 9005 the same bulb?

No, H11 and 9005 are not the same bulb. They are two different types of automotive headlight bulbs with distinct specifications and applications.


Explaining the Differences Between H11 and 9005 Bulbs


H11 and 9005 are both halogen headlight bulbs used in various vehicle models, but they have some key differences in their design and functionality:



  • Bulb Size and Shape: H11 bulbs have a larger diameter and a different shape compared to 9005 bulbs. H11 bulbs are designed to fit into specific headlight housings, while 9005 bulbs have a different mounting configuration.

  • Wattage and Brightness: H11 bulbs typically have a lower wattage (55W) compared to 9005 bulbs (60W), resulting in slightly less brightness output.

  • Beam Pattern: The beam pattern and light distribution of H11 and 9005 bulbs can vary, with H11 bulbs often providing a wider, more uniform beam pattern.

  • Compatibility: H11 and 9005 bulbs are not interchangeable, as they are designed to fit different headlight housings and electrical systems in vehicles. Using the wrong bulb can result in improper lighting and potential safety issues.


It's important to always refer to your vehicle's owner's manual or consult with a professional to determine the correct bulb type for your specific make and model of car or truck.


Choosing the Right Bulb for Your Vehicle


When selecting a replacement headlight bulb, it's crucial to ensure you get the correct type for your vehicle. Using the wrong bulb can lead to issues such as poor lighting, electrical problems, or even damage to the headlight assembly. Always double-check the bulb specifications and consult with a reputable auto parts store or your vehicle's manufacturer to ensure you get the right replacement bulb.
