First thought when I just looked at the solarstorm x3's was Johnny 5 :D
solarstorm x3 from ebay or china ( aliexpress etc) I sue for commute along a canal path and for MTB night rides. Just make sure they are dipped on the roads. You will be seen,
I've been using Xanes lights for a while and pretty happy (apparently cannot post links to it as banggood seems to be banned).
Any recommendations, which are value for money?
