Since the Miata is now gone, my van is getting more attention. For the longest time, I've been wanting to change out the H11 low beams for H9 bulbs. Not difficult in most situations, since minor modification to the H9 bulb is all that's necessary. However, the Sedona takes the rare H11B bulb, which is a rebased H11 bulb. So aside from needing to splice and solder on an actual H11 socket and modify the dust cap housing slightly, it was a straightforward install. I used the plain old Philips H9 (made in China). The difference in light output is insane... no other way to put it. The light is whiter, much brighter, and much more usable. Many people insist that this mod increases the downroad and side throw of the beam; I found this to be somewhat true. What really happens is that the beam pattern is still identical, but everything within that beam pattern is more intense, including areas that were scarcely lit before. The projectors on this van don't utilize any squirrel spotters, FWIW. The cutoff is still as sharp as it was before, and I did not have to re-aim the beams. I don't foresee heat being an issue, since the headlamp assembly is quite large and has a lot of dead air space inside. If your vehicle uses the H11 bulb, give this mod a shot.
