Best advice, LOL, is "don't leave the key on." On a Mopar system you'd be replacing the coil, the ballast and the ECU, or at least one of 'em, likely.

On a side note, a cousin of mine, ZERO mechanical ability back then, had one of the early Jeeps with electronic ignition. He did NOT understand the difference between "accessory" and "run" on the switch. He had replaced SEVERAL (three?) ignition boxes, and asked me one day if I knew why. He did have kids so I asked,

"Anybody leaving the key on when it's parked?"

"Well I DO listen to the radio sometimes"

"Ya, but not with the key in run do ya?"

And, I get that "deer in the igntion switch" look. That was the end!!! of the bad!!! ECUs!!!
