I poked around on prostreetlighting and found this, which they advertise as "HID" but really is just a blue tinted halogen H4 bulb. Real HID's have a ballast box to run the HID bulbs. If this is what you bought (except in the 5 3/4" version) then you should have functioning high/low beams just like normal bulbs since that's all they are. Depending on the quality of the housings you will probably have a low beam cut-off too. The blue tint actually reduces the light output compared to clear bulbs, but they get away with advertising them as "90/100W output from a 55/65W bulb" since most people are replacing old sealed beams and the new housings will make any regular wattage bulbs seem alot brighter than the old sealed beams.
