Tell me about your ballast resistor failure.

This is all overblown. I've only replaced one or two since my first 69 RR I bought in 70. I've known lots of Mopar owners through the years, and many of them didn't know WTF a ballast WAS. I think the biggest failures are caused by 1...folks leaving the key in "run" or using "run" to operate the radio instead of "accessory" when stopped, or 2...water breaking the ceramic, road splash, rain, etc, and then at some point, vibration finishes the job
