H11 vs H8 vs H9 vs H16: Car Light Bulb Comparison
Introduction
This article provides vital information about H11, H8, H9, and H16 bulbs, offering detailed insights to help you grasp the similarities and differences among these four specifications. Whether replacing existing bulbs, upgrading to LED lighting, or making post-purchase adjustments, this blog equips you with valuable information.
H11, H8, and H9 are commonly used sizes for automotive headlight bulbs, while H16 bulbs are less prevalent and typically found in a limited number of American vehicles. Notably, the European market utilizes a different H16 bulb, the 5202, which has no connection to the American H16.
Bulb Specifications

Beam Type | Low Beam / Fog Light | Fog Light | High Bean | Fog Light |
Key Similarities and Differences
Shape and Connectors
H9, H11, H8, and H16 share the same connector because they are identical bulbs with the same plug. As illustrated above, it has a traditional right-angled structure: two closely spaced prongs enclosed in a plastic oval casing, which includes a plastic divider at the center and two tabs on either end.
Filament Type
All these bulbs feature a single filament design.
Voltage Ratings
They have a rating of 12 volts, a standard for most automotive headlights and fog light bulbs.
Lighting Technology
H11, H8, H9, and H16 are available in halogen, LED, and HID lighting technologies. Although factory versions are typically halogen, all can be upgraded to LED or HID bulbs.
Applications and Usage
In various automotive applications, each bulb serves a distinct purpose:
- H11: Widely employed in low-beam headlights and as fog lights.
- H9: Typically utilized in high-beam headlights.
- H8: Commonly designated for fog lights.
- H16: Frequently positioned in fog light applications.
Brightness
The luminosity of standard halogen bulbs varies among different types:
- H11: 1350 lumens
- H8: 800 lumens
- H9: 2100 lumens
- H16: 500 lumens
It's essential to note that these values are indicative and may vary based on the manufacturer. Additionally, it's worth mentioning that in comparison to halogen bulbs, LED bulbs generally offer even brighter illumination.
Average Lifespan
The H8 has a life of 320 hours, H9 has 240 hours, H11 has 270 hours, and H16 has the shortest lifespan at 150 hours for basic halogen bulbs.
Socket/Size Compatibility
The power cord and socket for H8/H9/H11 LED bulbs are universal, with the only difference being the width of the PIN pin on the power cord and the width of the clips on the card holder. Users may need to adjust the spacing of the PIN pins during installation.
Upgrading to LED
While the factory versions of H11, H8, H9, and H16 bulbs are often halogen, upgrading to LED bulbs is a popular choice. The advantages include increased brightness, longevity, and energy efficiency. However, it's crucial to ensure compatibility and make informed decisions based on individual preferences.
FAQs
For halogen bulbs, converting H9 to H11 involves removing a small tab from the inside of the bulb base, allowing the factory H11 harness to plug directly into the H9 bulbs.
For most LED bulbs, H11, H8, H9, and H16 share identical connectors, as they essentially feature the same bulb design with a consistent plug.
