Same law in Michigan. Front light, 500 feet visibility required, rear reflector, 100 to 600 feet visibility with low beams pointing at it, red light optional.

Personally, I think rear lights AND reflectors should be required. Lights work in situations where reflectors don't, but reflectors work without batteries.

I have a Magicshine up front, a Dinotte and a Superflash in the back, a 4" DOT truck reflector and about 8 feet of white reflective tape all over the frame, and I wear a reflective vest, so I think I'm covered.

I'm thinking about picking up a NiteRider Cherry Bomb, putting that on my helmet, then putting my two Superflashes on the seat post angled out at close to 90 degrees, with the Dinotte pointing straight back. In addition to reflectors.
