Our fogs/driving lights are H4, but it says dual filament (one for "fogs", the other for hi beam, right?). I've been looking around, and I can't seem to find H4s that are dual filamanet, then I did some more reading and read that H4s are basically dual filament (meaning they are all dual filament). But each new thing I read says differently, and even one of the sponsors I contacted whos selling them didn't really answer my question

So, are ALL H4's dual filaments? I've been trying to replace my OEM yellow ones, but dont wanna lose my hi beam ability.

 

H4, HB2, and 9003 are different names for the same bulb. They all are dual filament, and will fit any light housing that is marked H4, HB2, and 9003. I just upgraded mine to an H4 HI/LO Bi-xenon kit. I still have the function of fog and high beams with one telescopic HID bulb in each housing. Here's a link for some info on the bulbs, and why there are a few different names for the same bulb.

It's pretty easy. The kit will come with everything you need. It's mostly plug-in-play. The kits will come with detailed instructions. If you get a kit and have problems with it, hit me up, and i will guide you through the install. Don't worry, you can't mess it up.
