FYI putting chrome valve stems and center caps, and lighted caps on bikes actually throw the wheel balance off, and if you look @ a set thats been on there for a while, instead of straight up and down, they are horribly slanted, and start to leak.I know from experience with my 2 hayabusa's. My drag busa was mostly chromed w/ chrome wheels, and w/ just chrome valve stem caps it threw the balance off. My road busa is fully chromed....whatever isnt painted is chromed, and w/ chrome valve stems and caps, it threw the balance off so bad after a while the bike shimmyed around 150+.
I say this because the lighted ones are actually heavier than the chrome ones.
I hope i helped a little.
