When you turn the key to on, the dashlights have to come on and go off when you turn it to the starting position. Make sure you have a good battery first. No dash lights indicate a bad ignition switch. Check all fuses and relays. But I am pretty sure it is the ignition switch.

You have your headlight control set to auto and your light sensor on the top of the dash is either faulty or fallen out of it's bracket and can not sense light.. turn your headlight control to off and use your headlight switch in manual till you get your sensor problem fixed..
