Andrew & I have created a bit of confusion about the proper OEM configuration of the DeLorean's headlight operation, so I'm posting an explanation to the list to answer the following question asked by a list member: "Our DeLorean is also set up so all four headlights come on with the brights selected. Are you sure that isn't a factory set up?" Yes and no. You could very well have the factory setup and not realize what is switching on and off. The low beams have two lights in one. In the same headlight fixture there is a low beam and then a separate high beam assist. When you switch on the high beams, the dedicated high beam fixtures turn on (the ones closer to the fake grille) while the outer low beam fixtures switch modes so that the low beam portion turns off and the high beam assist portion turns on. So it may appear that all the filaments are powered when really only the high beams and high beam assists are on. A modified car would have ALL the filaments powered while the high beams are on. The way to tell for sure on your car is to pull up to a wall with the headlights on and flip on your high beams. Flipping the lever forward (away from you) should latch the high beams & high beam assists on while switching off the low beams. Pulling the lever toward you should switch the high beams & high beam assists on but not interfere with the low beams -- meaning that if the low beams are off, then they stay off. If they are already on, then they stay on. But be aware that pulling the lever toward you is a temporary 'flash' that should work even when the headlights are off. Confusing eh? To further complicate matters, there is a wiring variation on the brake lights so that some cars allow the brake lights to work while the ignition is off while others only work while the ignition is on. I'm not sure if this same variation also applies to the high beam 'flash' working while the ignition & main headlight switch are off. Try yours to see. If you want to simulate what it looks like to have your low beams modified to stay on, then turn your headlights on and pull & hold the turn signal lever toward the driver. This will power ALL the headlight filaments simultaneously. If your lights are aimed at a close wall, then you should see a total of six bright spots (three per side, two of which are coming from each low beam fixture.) There was a discussion about this on the DML last year (I think). Someone was asking why the low beams shut off when the high beams turn on (that might have been me(!), but I don't remember particulars like that). DMC Joe spoke up and said that the reason for it is that having the area in front of the car lit up causes the iris to constrict making it harder to see distances at night. The DOT determined that people could see distances better if the foreground was darker. So that is why the low beams don't run with the high beams. I have seen mail order catalogues (such as JC Whitney) that sell relay kits that keep the low beams on with the high beams claiming that this is safer. The ads read something to the effect of, "Why turn off your low beams when you can have more light?" But the fact of the matter is that 'more' is not always better. Now the situation with the Xenarc HIDs is different. Those have to stay on with the high beams because it takes a minute or so for them to warm up. Switching them off while the high beams come on would be dangerous because then you would have to wait for them to warm up each time while they come back on. But keeping them on is not a disadvantage because the beam pattern with it is tightly focused in a horizontal plane. They don't light the immediate foreground as brightly as standard (American scatter style) headlights. In comparison they are more like "short range high beams". Then when you switch on the high beams with HIDs, they effectively extend the range without using traditional high beam assists. In a sense, the high beam fixtures ARE the high beam assists. I hope this makes sense. :-) Walt Tampa, FL
