It's obvious you have a short, now where the short is is the question. Try having someone press the locks on the passenger side and see if it does the same thing. If it doesn'tthan the short is probably in the driverside door. Then take your door panel offand look for any puncture marks in the wires. The reason that would happen is because when you send power to the door locks, the electricity gets discharged though the ground side; but if there is a short somewhere than the excess power gets divertedlike in your case to your dash and head lights.If you can't figure it out than have a mechanic look at it.

I've come accross symptoms like this, and found an aftermarket alarm system, to be the cause.

Thats a good point, I didn't think of that.
