The lights are automatic for your daytime running lights AND your regular head lights. There is a light sensor on your dash that knows when it get dark. When it's dark your headlights will automatically come on, daytime lights turn off and your dashboard lights will dim as a result, since you no longer need them to be that bright when it's dark. As far as the parking brake, it triggers your daytime lights to turn off, so when you disengage your parking brake, they will turn on for normal driving. All of this is a good thing because you never have to worry about turning your on/off...ever.
Someone has changed the wiring.
Well if you pop the hood and look above the headlights you will see a screw. It may be a hex screw. Now if you need to raise the lights tighten the screw and if you need to lower the lights, loosen the screw.
On the lancer its easy just pop the trunk open find out which lights are out and take the screws out that hold the lights in place and pop the bulb out that isn't working by turning it and replace it.
get regular headlights and mount them on
One question I'd have is whether or not your tail lights are working. I had the lights on my dash go out (the shifter lights still worked though) and my tail lights and parking lights were also out. After much investigation, it ended up being that the turn signal switch had gone bad. In order to replace it, you need to remove the cover around the steering column - we couldn't get the lower part of the cover off and subsequently also had to pull the steering wheel, then remove the turn signal switch (which also controls the headlights, parking lights, tail lights, etc), pop in a new one, and enjoy a life of dash lights and tail lights once again.
The whole headlight on these 03 silverado is not that hard to take it out. When you pop the hood open as you look on the headlight there should a long piece of tube metal that is holding the headlight onto your car. As I recall there shouldn't be any screws or bolts holding the headlights. That is for headlights, not "Daytime Running Lights". Still looking for answer!
There are two clips on the headlights. they are at a 90 degree angle. use a flathead screwdriver and slightly pry upward at the notch. they pop up and the headlight comes out.
Pop the hood, take off the front grill, remove old lights, replace with new ones. The headlights will probably be mounted on a frame.
your car is broke
there should be a button by the steering column that enables you to bypass the motor in the pop up headlights. Try pressing that and see if they go down.
