Thanks for the steady trickle of orders chaps, the Black ones are proving more popular, I've only sold one Gold one.
I think the Gold suits the Chrome rim and shiny reflector better and blends in with the other Brembo bits and pieces on a Monster. The Black was intended to be a better option for LED units.
Ah well, looks like I will be converting some of my large Gold stocks to Black...
Please don't forget to review the lights and bulbs that you choose, so we can tell which ones shine and which ones fade.
