Unfortunately, under California law only law enforcement vehicles; including bicycles, are allowed to display steady or flashing BLUE lights. The other colors are okay. Check your own state DMV laws for color restrictions. This is from the California DMV website. Note Section B... V C Section 21201.3 Bicycle Lights Bicycle Lights 21201.3.
