Planet Bike has an amber 3LED front blinkie too. I've clipped one onto each front pannier on my Cannondale:
Also, for daytime visibility when commuting, how about a neon-lime ANSI Class II or Class III vest? And run your HID too, can't hurt. The vest doesn't need frequent washing, and can fit over whatever layers you need for the day's weather. Mine even fits over my Camelbak.
