Porsche 914 & 914/6 Fog / Driving Lights: 1970 - 1974
Hella TN4
The insert on the fog light switch changed from the
green style to the amber version shown here prior to the 1973 model
year, at which time only the Hella TN4 fog lamps were used. The 1975-1976
rectangular Bosch lamps were also controlled with this switch and insert.
