In the states anyone can have clear or amber strobes. It's illegal to have anything else.
I've got a set that I'm going to install in my brakelight. While it's illegal. I don't see getting a ticket over something that's for my own safety. (Unless the officer is trying to find something to bust you on)
I have considered some strobes for mine for a while. I would like to start doing escorts for bicycle races and would like some flashing lights.
I want alternating amber strobes fitted to the turn signals. Does any one know where to get a setup like that? Presumably I would like the same style that emergency vehicles have where the strobes alternate 3 flashes on the left and three flashes on the right.
