This Hella lights advertisement was often put in the fog light boxes sold in the 60ies to 70ies.
The advertisment offers twin-tone horns, compressed air horns, wiper control swtich, tubular ventilator and the Hella car fan.
There is also a nice picture on the ad from the German Autobahn with vintage Volkswagen like Karmann Gia, VW Bug, Type 3 and T1 Transporter Bus.
