02 Passat headlamps: Which bulbs are lit when?
Silly question, but I guess I've never stood in front of my car and looked
at it when the lights are on 'til now. I guess there are three states (not counting the fog lamps): 1. DRL 2. Normal headlights on 3. High beams on It appears that from the front at least, states 1&2 are the same, with the outer pair of lamps lit, while state 3 also brings up the inner pair. Right? I expected the DRL mode to be reduced intensity, but that doesn't seem to be the case. -- Bert Hyman St. Paul, MN |

The DRLs might be slightly reduced but barely perceptible. I know on my Eurovan they're almost no dimmer to the naked eye but if I put a voltmeter to the wiring the DRLs are slightly less voltage than my low beams. But yeah...they're not really any dimmer from a "does it matter" standpoint. |

As I recall the DRL's are the high beams on at 70%. A 30% reduction in power translates to something like a 40% reduction in brightness and unless you are looking very carefully most people will not detect the difference, but the life of the lamp is extended. In addition the light spread is wider and higher to provide better warning to on coming drivers and more light to someone standing in front of the car. -- Joseph Meehan 26 + 6 = 1 It's Irish Math |

BTW I have replaced my original switch with a European version. I have: 1. DRL 2. Parking Lights 3. Normal headlights on 4. High beams on With the option to turn on the fog lamps at any setting. Which means in heavy fog or snow, I can use position #2 with fog lamps for the best possible vision. The higher mounted head lights on normal or high beam bounce back too much to be useful in fog or snow. -- Joseph Meehan 26 + 6 = 1 It's Irish Math |

Unless the laws have been changed recently, high beams plus fogs is illegal
almost everywhere in the US. If you are in the US.

It should be easy enough to tell (if you don't have someone handy to look at the bulbs which you switch modes) by pulling up in front of a wall and going through the settings. On my '03 Passat, the DRLs are the low-beams, running at (slightly) reduced power. The difference in brightness is minor but noticeable. -- Mike Smith |
