Capn, it makes it easier for you to see them at night. The state now feels you can line them up with your hood much quicker to get a better "hit". The state of Michigan is tired of those crippled deer running loose. They want you to get them the first time.
Michigan is also coming out with "Glow Green" and "Florescent Orange" in the near future. Some say that Michigan got the idea of multiple colors from the folks at M&M candies. Look for them on your local interstate and also in different flavors.
Tastes like chicken!
