Johnny Lightning were kinda like Mattel's Hot Wheels except not as popular. They were out of business by 1971 while Hot Wheels continued to thrive. One thing they did have over Hot Wheels however was that they were FAST.
I'm talking fast.
To paraphrase one of the catchphrases of the major motion picture Action Jackson, if I may - Johnny Lightning cars were, "Fast. Faster. Fastest."
Or at least that was their claim to fame.
