Running light ala Knight Rider

do you know this running light …. whether the Tüv becomes evil when you install something like that ? have to install 10 small LEDs in the front of my Mazda 323F in the radiator grille, which are controlled by means of resistance and various other small parts. you can also control the speedykelit !!! question is only .. what does the Tüv say for such a thing ?! it is mainly for show purposes … I don’t want to have the thing turned on every day and thus drive through the other !!! have you there sc hon experiences made ? achja …. and what about the lighting of the amatures ? so tacho etc … can one illuminate the naturally also differently ? had someone ever had so far on ? mfg Hacky
