Point detail

(c) It shall be one signal with no interruption and no vertical oscillations (e.g. not more than one change of direction along the vertical axis). The distance between two adjacent/tangential distinct parts of the light emitting surface  of  the  sequential  direction  indicator  shall  not  exceed  50mm,  when measured perpendicularly to the reference axis, instead of the values defined in  paragraph  5.7.2.  of  UN  Regulation  No. 48  or  paragraph  5.7.2.  of UN Regulation No. 86 or paragraph 5.6.2. of UN Regulation No. 53.

These interruptions  of  the  signal  shall  not  create  any  overlap  in  the  vertical  axis between the different parts, from inboard towards the outboard of the vehicle, and shall not be used for any other lighting or light signalling functions;
