your high beams are flashed or turned on? I tried looking at the lights while my wife played with the switch and I damn near blinded myself. :D The reason I ask is that I am retrofitting HID projectors, bulbs and ballasts in the housing within the next two weeks and just looking for the time to take the headlights out. It would be hell on the ballasts if the lowbeams went off everytime I flashed the high beams. And it would also cause the ballast to shut off and restart causing near darkness while driving until the bulbs warmed up.
Thanks all in advance,
Laurence
p.s. Could some of you guys with a helm book take a peek and let me know if there is a circuit that is on when the headlight switch is turned on and unaffected if the high beam is flashed or turned on? |

i believe the pilot uses an H4(?) bulb which is one bulb for both high and low beam. if thats true then you'd need a bi-xenon retro if you want to keep the high beams.
res-pilot did a HID retro a while back

Like all cars (properly working ones that is) the low beams go off when the High beams are on. |

My Lexus isn't like all cars, then. The low beam HIDs stay on when the high beams are on, causing this weird yellow overglow over the blue cast of the HIDs.:confused: |

I would bet (just a guess from all I have seem) that is the low beam 'light' stays on, it will either shift pattern or brigtness when you put on the high beams.
So you full brightness, low aimed beans are not on with your high beams.
Remember the old 4 headlight systems. Even then the "low" bulbs were actually "low/hi" with two filliments and two patterns. |

The system in my RX 330 is one where the HIDs are low beams, and the halogen bulbs next to and closer to the center of the vehicle serve three purposes. During the day, they are DRLs. When the HIDs come on, they stay on, but begin to look like markers (parking lights, even less power than DRLs), but when I hit the high beams, they kick in full power, and nothing ever visibly changed with the HIDs. No pattern shift, no brightness degradation, nothing. Weird.:cool: |

Some vehicles (some VW's come to mind) have a single HID bulb for high, low, and DRL's.
The VW system uses a shutter in the projector housing to alter the beam pattern from a low beam to a high (main) beam pattern, and would presumably either reduce power, or another shutter that reduces the output for DRL's if they are at a reduced intensity.
The downside to this system of course, is that you introduce moving parts into the lighting system.
But you should have a leveling system for the projector housing already |

I thought that the low beams and the high beams are in the same bulb. The low beams are a pair of filaments, and when you turn on the high beams, another filament is turned on for even more power. Somehow they must place the filament in a location where its light is spread in a different pattern. Anyone?

You got it!
The placement of the filament relative to the reflector, lens, and any shields determines that pattern. |

I just wondered if the low beam filament was shut off for the high beam filament. Or, do they both stay on during high beam mode?
I will test with a multimeter to find out.
I already have the bixenon projectors off of a 7 series bmw and bulbs and ballasts and wire harness. I just needed a constant on signal when the lights are on regardless of high beam or low beam. |

I believe that when the high beams are on, all the filaments in the main bulb are on. When the ordinary driving lights are on, only two of three filaments are.
Correct me if I'm wrong!
Thanks,

The LOW BEAM GETS SHUT OFF.
But remember, the Honda system switches the ground instead of the hot. |
