Turn signal rear with light bulb(s)

Have my Ateca already 9 months, and I have only now noticed that the turn signals are operated at the rear with normal light bulbs. At my Xcellence series equipment rear lights in LED technology I am appalled Is this also the case with you, or do you not know that yet? Check it out ! My opinion: if already LED technology, then all lights in LED. What do you think about it ?
