I'd agree that if it shut off before somewhere there is a connection for full time power to the ignition from something you connected when you hooked the lights up.

One question, was the alternator on the truck previously and did it shut off when the alternator was on it before you hooked up the lights? That I ask because if you have the exciter wired to the ignition switch without either a diode or an idiot light in the circuit the feedback from the alternator will keep power to the coil.

Otherwise go back to where you hooked into power for the lights and check there to see that you don't have that wire or terminal making contact with the ign wire or terminal.
