When I saw amber I was thinking thats not a good color for a light. Amber is the signal color, amber means your signaling to turn. Ever see some of these never cars which use amber as the DRL, every get one as a rental. Everyone pulls out in front of you, they glance your way and see amber and assume your turning so they are safe to pull out.

I have the red PB superflash on the back of mine BTW.
