My brother and I got stopped today by a Los Angeles County Sherriff. My brother's FZ1 has blinking LED running lights that go solid when you hit the brakes. This was the initial reason for the stop. He has a bobbed rear fender and the license plate up against the tail light like most guys are doing. The deputy said that they have been instructed to start enforcing lighting and reflector mods to motorcycles. Here is the bad part. It is no longer a simple fix-it ticket. It now carries a fine and return to stock ticket. He stated a burned out light is a fix-it ticket. A modification is deliberately changing a DOT approved lighting system. This will include clear lenses that are after market. We spoke for about 15 minutes and the officer kept pointing to my KRS as an example of what a stock bike should look like including the stock exhaust system. (He checked out both of our pipes) The Deputy said that many young riders are modifying their bikes and the LEO's are starting to enforce vehicle codes aggressively. He said anything other than paint jobs will get scutinized for violations. He was pretty cool about the whole thing and let us two older guys 2 miles from home off with a warning but said that my brother should think about going back to the stock lights to avoid another chance for a ticket. Food for thought for any California riders. We were not speeding and the only thing he saw was the blinking tail light as he passed us going the other way. This was enough to come and chase us down and give Bro a warning. I have LED running lights and a blinking brake light. He said there were legal (like pumping your brakes) because they showed you were indeed braking. The running lights blinking are subject to confusion as to what a rider intends to do. I did not agree or disagree with what he had to say. He just wanted us to know a crack down on mods to bikes are underway.
