What I did in my old car was to cut the ground wire for the headlight switch and hook it up to a relay with a wire that had 12V when the ignition was on. When the ignition was on, the two sides of the headlight switch ground wire were connected, allowing control of the lights. When the ignition was off, the ground wire was disconnected from the switch, thus disabling it. If you want, I can look up the wire in the service manual, but I don't know if this method will work in the Vibe.Here's a post from another forum doing what I described above:

The chime didn't work in my old car because the remote starter made it so the car was still running when I got out.Ideally, I'd want a setup such that the lights could be turned on whenever you want, but would automatically turn off if the car is turned off. To turn them back on while the car is off, switch off the lights then back on.
