lol... Man, The reason for an H4 bulb being "dual" is because of the shield and filament inside the bulb...
If u decide to get a McCulloch H4 aftermarket kit, and WHEN the bulb DOES break... You will need to get ANOTHER H4 HID bulb... Or, New harness.
Since aftermarket kits are now illegal, It will be very hard for you to find a Bi-H4 bulb... A lot of them are only low beam bulbs.
cough... Aftermarket HID Kits suck... cough
Wait... What does OEM mean? Oh.. Wait... Original Equipment Manufacturer? Hmm... Origional... or Aftermarket... >=]

H4 HID:
An H4 is constructed to use the upper portion of the reflector only when low beam filament is on. An internal shield in the H4 bulb will reflect light going downwords towards the upper portion. When you turn high beams on, low beam filament will turn off and high beam filament lights up. It is mounted a little away from the low beam filament, so the beam will hit the road further ahead.
So what happens if you slam an HID bulb in there, correctly mounted in the focal point?
Very simply, the entire reflector will be used and even the orange light that normally emits from the lower portion of the HID bulb will be visible on the road. In other words total useless light. By having the HID return wire of the bulb turned down and using an appropiate shield made in stainless steel or aluminum should correct most of it.
Many kits out there makes you give up high beam. Some people claim that HID will give you the extra light, so high beam becomes unneccsary. This is not true.
