Some things are worthy of a ticket Dave, but NOBODY could agree with giving a man a ticket for a blown light bulb, specially when he had the new one right in the car with him and showed it to the cop writing the ticket.
Even is he beats the charge...which I'm sure he will...the man is still out a bunch of $$$$ from work, plus all his inconvenience.
Certainly has nothing to do with you, but this thing is a total farce.
