What is the "usual" fine in Folsom for running one of those metered lights.

Did'nt see the meter on light one afternoon around 3:30 because the sun was in my face and when I got to the actual light it changed to red (not any cars in front of me) Anyway didn't have time to stop without braking dangerously. A motorcycle highway patrolman behind me and of course I got the ticket. He said and I quote"don't worry- it will only be about $30 and then you can sign up for traffic school so your insurance won't go up". Well the fine came in the mail and it was a whopping $371. What's up with that? Is that a mistake or the usual fine? Please email me back now or at janethandel52@hotmail.com. Thanks!
