1 for the xenon
1 for the halagon high beam
1 for the blinker
1 for the ???

 

umm.. i always thought it was 4 xenon bulbs..
2 low beams
2 high beams.

 

i read somewhere that theyre "city lights" so im guessing driving lights? i guess they're like those extra lights on the Lexus RX300 or something...

 

cornering light when the turn signal comes on?

 

4 bulb xenon..
2 low 2 high..

 

there are 4 bulbs on the left side and 4 bulbs on the right side of the headlight cluster:

1 xenon arc (HID) bulb for the low beam
1 regular halogen high beam
1 behind the orange lens one for the turn signal
and 1 bulb behind the clear lens for ???

cheers

 

Hm...has it occured to anyone that the light might be a reflector?

 

probably just a running lights...i meant...the parking lights....whatevers....

 

A 4-bulb headlight system refers to separate high and low beam bulbs. One of each on both sides = 4 bulbs. Only the low beams are HID, the high beams are conventional halogens.

 

2 for HID Low Beam
2 for Reg High Beam
2 for Turn Signal/Marker light?
2 for (Drum Roll) Day time running lights (like the ones on the I-30)
I think that's what the 4th set is for...

 

I thought those 4th set of lights were the flash-to-pass lights. You can't flash the xenons because they take too long to heat up.
