Been looking for awhile after getting some tail lights that so happen to have a blue light, and I'm finding marketing material stating that blue tail lights are illegal, but all the laws I keep finding that prohibit displaying a blue light say "motorized vehicles," and usually "flashing." Based on what I'm finding, a solid blue light can be on anything, and a bicycle is not motorized, so it can show blue in either flashing or solid. Where are these vendors getting the info on the nonlegality of blue from?
