the system. 2 wires on the back of the ignition key

lock cylinder would need to be replaced. I will send
a link to a page in our site that shows this.

want , now my lights have gone out and i cant drive at night.

Assuming you have either replaced or have good headlamp
bulbs, there has to be an electrical issue affecting the headlamp
operation. There is an ambient light sensor on the dashboard
that detects when it is dark and automatically turns on the lights
for you. If the headlamps are coming on by themselves at all
different times, day or night, that sensor could be bad.

Also, you could have either the headlamp switch or Driver
Integration Module (DIM) with an intermittent electrical problem
that is making the lights act up. There is also a relay in the
underhood fuse block for both the low beams and high beams
that could be failing. If the bulbs are known good, an no obvious
thing is causing your problem, you would need to get a
schematic of the headlamp wiring and start checking wires for
