I would agree on the bike registration bit. I'm guessing there is no visible way to know that law even exists, AFAIK most of those laws went away well before I was born around here.

And also agree on the lights would be better to be a "fix it" type deal, at least on the first offense. I blew out a headlight on my truck, literally facing a cop at a red light. Watched it pop, saw the left side go dark in front of me, and watched as the officer pulled a U-turn and pull me over. Fixed it the next day, took it in to prove it was done, and ticket dismissed.

But all in all, I don't know LA fines, but it really isn't hard for me to see how four infractions could hit that amount.
