Hi, its been 20 years since I saw the reno nevada hot august nights car show that had all kinds of hot rods including tons of 57 chevys. Some of the rat rod open engine cars had neon glass tube lights inline with the spark plug wires. I cant seem to find any videos or information good or bad on them. The wife wants me to find videos on them. Anyway, these cars looked cool at night, when revved. They had the look of spider legs being 8 cylinders. All I get on youtube when searching is the dam dodge neon plug wire tube repair. Any drawbacks to using this type of setup?
