Fine for taillights I guess if you want... will NOT work as a headlight.
Just look up nate bandits headlight mod - you should already have 12v rectified power if you're considering this and halogen is better

these are very cheap lights and arent too bright to begin with, the LED's start to burn out one by one in a matter of weeks. I have this in my head light on my pug, moby CDI....i also have one in my puch tail light, as a tail light it works great, but as a head light your better off taping a 99 cent flash light to your handle bars cause you will get the same light output!
Useless as a headlight 
dont do it
