Not all states allow flashing lights other than red, could be trying to reduce their potential liability for illegal lighting choices? (Of course, white strobing lights are illegal many places, too, and I can't recall any headlight manufacturer warning not to use strobe mode where it's against the law, so maybe red is simply easier or cheaper?)
