Perhaps an aftermarket company will develop a clear reflector insert.Dutch said:In the US they are orange indicators, in Europe orange reflectors.
Indicators on the side of the car are not mandatory in Europa. but they could not afford to build two arches (with intrusion for the US and without intrusion for Europe, so they simply put reflectors in). White reflectors would have been nicer though (or chrome!). I don't think you can find parts, the shape is unique to the Karma. Maybe you can have them sprayed. Or even chromed.
Until then, painting the reflectors in body-color paint should look better. However it could be a difficult match with some of the diamond dust paints.
