:rolleyes: Hmmm, this is my first try at this so forgive me if I do it wrong...
Does anyone know if it is legal to drive in Southern California with lights on
Your under carriage? I have blue neon lights that I can turn on or off under
My truck! Thanks for the help!

I LOVE those things!
When I get a car, I want them to come with those lights.

But sorry, no. I don't know if it's illegal or not.
Perhaps it would be easier to just keep them off and go ask a car dealership or gov'ment official or something?
