H11 Bulb Comparison with Other Bulbs

H11 vs. 9005/HB3

H11 headlight bulb is not the same as the 9005 (or HB3) bulb. The H11 bulb is mainly for low beams while 9005 is meant for high beams. They also have different base plugs—the H11 has pins that are spaced closer together, and two tabs on either end.

Which one is more durable? You may find 9005 bulbs are generally last longer than H11 since high beams are used less frequently than low beams. For more details on headlight bulb longevity and the factors that impact it, check out our guide here.

So which bulb size is better? For the best results, consult your vehicle's owner's manual. It will specify which bulbs your headlights require. You can also use SEALIGHT automotive bulb finder to quickly locate the bulb that fits your vehicle. Note that you'll want to avoid swapping an H11 for a 9005 or the reverse since they are two different bulbs.

H11 vs. 9006/HB4

Although the H11 and 9006 (or HB4) bulbs are mainly used for low beams and appear comparable at first glance, these two bulb sizes are not the same. The H11 bulb has a large ring built into its base, whereas the 9006 bulb lacks this feature. Additionally, the pin connectors on the H11 bulb are positioned closer together than those on the 9006 bulb.

H11 vs. 9003/H4

The H11 and 9003 (or H4) bulbs differ in several key ways. The H11 is a single-filament halogen bulb, whereas the 9003 has two filaments. They also have different bases, tabs, and connectors, so they are not interchangeable.

H11 vs. H9 vs. H8

The H11, H9, and H8 bulbs share the same specifications, including bases, locking tabs, plugs, and sizes. If you're interested in LED alternatives, these bulbs are compatible and can be used interchangeably.
