I would start with the bulbs, make sure they are good and that they have power going to them. If there is no power at the bulb the problem is either your headlight switch or the dimmer switch.
I would start with the headlight switch.
And I would start with the fusesThat can happen when there is a bad ground to one of the lights.
A mis-wiring or short circuit somewhere between the controls, fusebox and lights.
Fuse for parking lights probably blown.
humm, This is strange because the DRLs (day time running lights) usually function from the same bulb as the headlights, in other words the headlights are always on so people dont forget to turn their lights on at night so if this is the case you have no problem. The only thing that might indicate a problem would be if the dash lights do not come on when the headlights are on, If this is the case then the turn signal switch could be at fault, otherwise I see no problem with the lights. Granted this could be the case or not but based on the question this is the best diagnosis I can provide, Good luck and I hope this helped
its on the left turn signal switch, at the end is the headlights, then one in is the fog lights, you twist it just like you would the headlights
true
You have some problems with electrical connections. Most likely the ground wire of the tail lights. Also, the left light may be burned out or have a POSITIVE wire connection problem.
This can be due to a bad headlight switch. If it goes bad, most of the time you have no dash lights or headlights
Push the turn signal lever forward
Headlights? Brake lights? Tail lights? Signal lights? Courtesy lights? Dash lights? Check engine lights? Need more info please.

I am actually having this problem.. here is mine... see if it relates to you. My headlights (on regular, low beam) do not work. I cannot get them to come on in the high beam either. But, if I pull the blinker arm forward for the passing flash thing, they light up on high-beams (only for as long as I hold the lights on). I have found the problem to be a thing called "Multifunction Switch". My car is a 1997 Ford Taurus G.... See if that helps you any. It was my underlying issue and mine is getting fixed tonight. :) Good luck
