I have fitted the kellermann micro 1000 indicators. for some reason the system will not let me upload a picture so u2u me if you would like pictures.
Bought the set of four from
www.carbonworld.de Quick delivery from Germany, my set (on a 748) needed the kellermann resistors to get the flash rate right, fitted a set to a 998 and did not require resistors.
The indicators are bright and E marked TUV approved etc the rear set are fitted with the carbon bracket that mounts behind the reflector
I think that they tidy the rear end nicely
