Well, having finished with the new headlights on the 1999 Grand Cherokee, I turned to the fog lights.
The bulb I pulled from a factory fog light was right angled and looked a bit like a 9006. But the arrangement of the three mounting tabs was slightly different, and it was marked 9055. This one is Sylvania, and appears to be marked 51 watt (not 50 or 55).
What grabbed my attention was that, unlike a 9005 or 9006, it had a transverse filament. What surprised me was that when I put the bulb back into the fog light and rotated it into position, the filament was horizontal, not vertical. I'd have that a rectangular fog reflector and lens would make better use of a vertical filament.
Is there a "better" or "best" bulb for the 9055? I know we're not looking for huge light output in a fog light, but some bulbs are better than others.
BTW the Grand Cherokee has a 5-1/2" aftermarket suspension and 33" tires in place of the stock 29's. So the fog lights are about 7-1/2" farther above the ground than stock. I'm not sure if they are much help in fog, but they do help me see what is to my immediate right or left, when offroad at very low speed. I do want to keep them in top condition.
