We used these on a CG125 cafe racer for my wife as they kept with the aesthetics of the bike but kept her safe with the incredible brightness.

Super indicators, unobtrusive and very bright.
They are used as standard on the Black Douglas Sterling

These tiny, discrete, powerhouse indicators are fantastic on custom builds. They are so small that they effectively "disappear" on the machine and yet they are incredibly effective in operation. So good I've bought them twice.
