[2] Headlamp cleaners shall not be considered as different in type because of differences in fluid consumption, cleaning period or the fitting of cleaning elements, provided that compliance with this Regulation is verified by the technical service responsible for the approval tests. This is also valid, if headlamps to be cleaned differ only by the filament lamp used, the design for left hand or right hand traffic, the colour of the light or by parts of the headlamp which do not influence the effectiveness of the headlamp cleaner. In the case of different filament lamps only the headlamp version with the highest power consumption is to be tested. a0c0
