These are amber/red with clear lens and the auxiliary color will be blue. It could be wired up to flash to blue. It will have an extra wire that shares a common ground with the other functions that when you give it power, it will override the regular light and turn blue. Most folks put it on a switch in the cab but it could be wired up to the flasher. Thanks!
