| ![]() they are all different bulb sizes. there isnt any better or worse. it just depends on which size your car has. h4 has both high and low beam built into one. h7 and h1.etc have only 1 beam. |

i dont think thats right. thats what happens in hi/lo HIDs. i dont think normal h4 halogens have this moving reflector thingy. |

| ![]() in a headlight there are two bulbs. the main bulb and a pilot/park bulb. right? so do these come as one set or do we buy them seperately? |

| ![]() thank you. so that means the main bulb and the pilot/park bulb don't come as a set and that you'll have to buy them seperately ? |

i have seen them as a set by philips. i thin they were blue vision. but you do also get the pilot bulbs separately for around rs150 or so for 2 leds. |

This is right. ![]() Quote:
In the H4 bulb, as akshay1234 has mentioned, there are two filaments : one for the high-beam, and the other for the low-beam. | |
