Don't waste your time looking for an H11. They are hard enough to find in stock form. Just install an H9 bulb in its place.

Light quality is measured in two ways. Color (measured in degrees K) and ammount of light measure in lumens. Lumens are more important that color. You can have a 1w LED that puts is rated at 4000k color, but its not going to put out more light than a 2000k headlight bulb. People get hung up on 4300k thinking the bulb is brighter. It is not. A bulb that has any kind of coating for higher color rating (4300k for example) will be dimmer (less lumens) than a clear bulb of the same wattage. Also there is no such thing as "55w=100". If you ever see that or "made in Korea" on a bulb RUN AWAY!
Real HID bulbs put out 4000k, 5000k etc. color light because thats how they are designed to burn in the first place. They also produce 3200 lumens. Thats what makes them so bright. At 2300 lumens, a stock 65w H9 bulb is just about the brightest halogen bulb you can buy.

H11 bulbs
These new single-filament 55w bulbs are quickly supplanting HB4/9006 in new low-beam headlamp and fog lamp designs. As is the case with other similar-but-different bulb designs—such as 9004/9007, 9005/9006, etc.—the H9 has different base keys than its H11 low-beam counterpart. Somebody goofed on the spec, though, for the difference between H11 and H9 base keys are insufficient; it's too easy to install an H9 bulb where an H11 belongs. The difference in light output between these two designs is enormous (1350 lumens from the H11, 2100 from the H9), so putting an H9 in place of an H11 will obviously cause the lamp to produce a lot more light. Some lamps are designed such that the optics will handle the extra light well, without creating excessive glare for other road users. Many, however, are not. As with H8 and H9, H11 bulbs are not widely available in the aftermarket.
