Question 3 prong and 2 prong with H4?

Ok i went into Lordco today and found the H4 conversion set i was looking for. So its bosch headlamp housings which hold an H4 bulb, but theres a problem (pardon my ignorance) an H4 bulb only has 3 prongs correct?, so if i buy these headlamps what kind of bulb do i use for the 2-prong bright-only lights? (H7 maybe?)

Or is my only option to buy one set of H4 housings and just have my low/high beams running H4 and keep the bright-only lights stock sealed beam.

Any info helps

As you figured out, 3 prong is low+high beam, and 2 prong is high only (or low only, in some cases).

H4s for low/high and sealed beam for auxilary high provides a lot of light, do it. The other common option is an H1 conversion, but it's really not necessary (you'll see).

so theres no high-only bulb i can buy thats gonna satisfy the 2-prong auxillary high beam requirement then?

Thanks for the info, i think im just gonna try the StarWhite bulbs at first, i cant afford the 90 dollar plasma ones.

What the hell? Man, you have a hard time reading.

I just posted that there are H1 conversions, that work just like the H4 housings. They're just not really necessary with good H4 bulbs.

All H4 bulbs are 3-pronged. This how they are both high and low.

You do not have H4 assemblies for highs.

Yeah, I'm on my second set of Hella H4s, just bought this pair this year. Great lighting, identical pattern to Euro Ellips which people spend so much on (I did once too, sold them for $450).

I also have a pair of Osram Silverstars here, shipped striaght from Europe. I'll get around to installing them soon.

I just got the BOSCH H4 Conversion done on my CHerokee, and Damn what a difference. I might just have to order me a set of these Osram bulbs you guys are talking about.

I managed to get a bosche conversion kit which consisted of 2 housings and 2 bulbs for 78 Canadian with staff discount at lordco. The kit came with 2 "Osram Bilux H4" bulbs. They are pretty nice indeed, but i cant wait for the silverstars. Oh ya, thanks to T.DOT for telling me about that auction.
