The pictures are misleading, the glow is the same colour regardless which you order - a light purpley, pinkey neon kind of colour. I dont know why they even sell them in different colours, you honestly couldnt tell them apart. Also theyre designed for schraeder valves, so to fit them on a presta valve you would have to mod them ie. superglue them onto a valve cap. I dont like the idea of something spinning up momentum on my valves though.
I opted for 4 spokelits, a fiery mix of 1 yellow 1 red on each wheel which i really like as its not too flashy but very very visable - a tad more pricey though. The best thing of wheel lighting is that it moves and so is very eye catching, an illusion which is lost if you use 1 colour per wheel and turn it into a stationary ring of light.
