Just keep in mind, even the brighest LEDs need a reflector or magnifier to really be seen at a distance.
I've got enough experience with LEDs in my pinball machines, arcade machines, house, car interior and car brkae/tails and so on to know. I've even built third brake lights for cars. I've experimented with many types to get the effect I want. CREE are the brightest and have a magnifier, those strips are not CREE but high power, there is a difference.
