How to Identify H11 Headlight Bulb

You can typically find the bulb number, "H11," stamped or printed directly on the side of the bulb itself. Additionally, the H11 specification will be listed in your vehicle's service manual, as well as in an automotive bulb guide or reference. The H11 is a single-filament halogen bulb with an L-shaped base. The plug resembles 9005 and 9006 bulbs, but the male prongs are positioned closer together. The narrow neck features three small spurs at the base, with one being slightly broader.

H11 vs. H8 vs. H9 vs. H16, What's the Difference?

These four bulbs are frequently grouped together because they share a similar base and physical dimensions, but they're not identical — and the differences matter depending on your application.

The H11 is the most common of the four, running at 55W and producing around 1,350–1,450 lumens in halogen form. It's used primarily for low-beam headlights, fog lights, and daytime running lights, and in many cases is compatible with H8 and H16 sockets.

The H8 runs at a lower 35W and outputs roughly 800–900 lumens — noticeably dimmer than an H11. It's mostly found in fog light applications and shares a similar connector to the H11, making it interchangeable in some setups, though the lower power output is worth keeping in mind.

The H9 sits at the other end of the spectrum — 65W and around 2,100 lumens, making it the brightest of the four in halogen form. It's typically used for high-beam headlights. Despite sharing a similar base, the H9 has a different tab alignment than the H11, which means the two cannot be directly swapped without modification.

The H16 is the lowest-wattage option at around 19W and approximately 500 lumens. It's used for fog lights and daytime running lights, and shares the same base as the H11. In LED form, H16 sockets are often compatible with H11 LED bulbs due to the lower power requirements involved.

The important takeaway: in their original halogen form, these bulbs are not freely interchangeable — wattage, brightness, and physical tab alignment all vary. In LED form, the picture is more flexible since LED bulbs draw far less power than halogen equivalents. That said, always verify fitment for your specific vehicle before purchasing. The easiest way to do that is with the SEALIGHT Bulb Finder — enter your Year, Make, Model, and desired application to see compatible options instantly.

A good H11 LED bulb will fit all three sockets and deliver significantly more light than any of them did in halogen form. Just confirm socket compatibility with the vehicle bulb finder before ordering.

H11 for Headlights vs Fog Lights

The H11 size is used for both headlights and fog lights on many vehicles, but the bulbs aren't necessarily interchangeable in terms of what you want from them.

For headlights, brightness and throw distance are the priorities. You want maximum lumens with a sharp cutoff so you can see as far down the road as possible without blinding other drivers.

For H11 fog light bulbs, the goal is different. Fog lights are mounted low on the bumper and designed to illuminate the road surface immediately in front of you — not the horizon. The ideal fog bulb has a wide, flat beam pattern. White (6500K) fog bulbs work well in clear or light rain conditions, while yellow fog light bulbs (around 3000K) are often preferred in heavy rain, fog, or snow because the longer wavelength reduces glare off water droplets.

SEALIGHT offers dedicated H11 fog light options in both white and yellow — worth considering if fog or wet weather driving is a regular part of your commute.
