I bought some of the red/white and thats just about the best for making you shine like a shiny thing.
I've just bought some of the black and while it looks bling because you can't see it, it aint a patch on the in your face white/red 3M stuff..
Its really worth having on a commute bike, especially if your a tool like me and you get caught out with no lights once in a blue moon over summer.
Least theres something gonna help make you obvious.
My maxlight commuter there, it has black stuff on the frame, then the stuff in red on crank arms/fork lowers is 3m stuff.
The 3m stuff works way better.
The best way to think of it is try making your bike look as strange as possible.
Something that reflects back at drivers that is an odd shape/configuration or just extremely obvious is more likely to make you visible.
Certainly less chance of the old smidsy.
