[MENTION=506482]Ralphinca[/MENTION], please don't use a front-facing red light. White is for front, and red is for rear. The wrong color is a "lie" and a disservice to other road users. Headlights are generally brighter than taillights, so if you want a flashing light to be seen, most headlights have a flashing option. And it's a good idea. I've received compliments from motorists on my flashing headlight which isn't even that bright. Motorists appreciate the early warning.
