FAQ:

Q: Can a H4 bulb be plugged into a H1 housing?

A: 1. Buy an H4 male connector (to plug into my stock H4 harness) 2. Buy an H1 female connector (to plug in the new H1 bulb) 3. Splice the two together so that the H1 bulb in the projector can be fed by my stock H4 harness.

Q: Why is a H1 bulb used for a projector?

A: THe H1 bulb was chosen for the projector because it is a very small bulb. THis would allow the projector to be mounted in larger reflectors via the stock hole with no modification of the hole. Everything you wanted to know about HID bulbs.

Q: What kind of bulb do I need for a HID projector?

A: HID projectors are designed for use with D1S, D2S, or D4S bulbs. The overwhelming majority of projectors use D2S style bulbs. The only HID projector that doesn’t use a D-series bulb is the Morimoto Mini H1, which is designed for use with compact H1 HID bulbs.

Q: Can a Morimoto mini H1 be used as a HID projector?

A: The only HID projector that doesn’t use a D-series bulb is the Morimoto Mini H1, which is designed for use with compact H1 HID bulbs. You must use the type of bulb that the projector was designed for. No, you cannot simply stick the bulb from your old HID kit in the back of a projector and expect it to fit or work well.
