Hi!,

the stop lamp LED in my rear wing has faded, it still lights up red but the lense is whitish. Is there anything I can do to recolour the lense? or does anyone know of a supplier for replacments?

depending on what sort of wing it is, you could call bob at ccs or the guys at awc and see where they get there led lights from. see if you can get a replacement through them.

Mine did the same, but to be honest I like the clear look.
Aside from replacing the complete led unit you could use red Lens Dye to freshen it up (available at many auto parts stores).
