Porsche 914 and 914/6 Fog (Driving) Lights and Lenses

Porsche® offered Hella fog/driving lights as an option on the 914 series: round lights for the 1970-1974 model years and rectangular thereafter. Furthermore, there were two styles of the earlier (round) style Porsche 914 US specification fog lights: those with Hella TN1-TN2 lenses and others with Hella TN4 lenses.

All factory Porsche 914 fog lights are mounted behind the front bumper and shine through cutouts in it (1970-1974 models had chromed or painted plastic fog light surround grilles that also served to mask the horns). The mounts pivot to provide a degree of adjustment. At right are comparison pictures of the two types of 1970-1974 Porsche 914 lights & components meant to highlight the differences. Each of the two “round” styles is separately described in more detail below. Note that the label comparison shows the TN1-TN2 lamp labels on top. The ring comparison shows the offset ring stripped of its gloss black paint to reveal the brass underneath.

The Hella TN1-TN2 fog light was available on the 1970-1972 Porsche 914 model years and the Porsche 914/6 models. They are round Hella lamps comprised of a semi-gloss black housing attached to the mount base with four unpainted brass rivets, a gloss-black painted brass trim ring, a reflector dish, a light diffuser, a 35 or 45 watt Phillips bulb, a 110mm Hella TN1-TN2 lens, a gasket, four wire lens clips, a wire grommet and a ring retainer clip (with screw). The lens has a horizontal offset about one-third the way up the vertical fluting. The trim ring also has an offset between the inner and outer circumferences so that the ring face is angled inward. The light diffuser that shields the bulb in the TN1-TN2 lamps is chrome. The Hella fog light switch in the 1970-1972 model year Porsche 914 and all 914/6 vehicles has a green insert.

P914 currently has a 1970-1972 Porsche 914 Hella fog light switch available in the SALES section.

The more prevalent optional 1970-1974 Porsche 914 fog lights are also round, 110 mm diameter Hella lamps with the same components as the TN1-TN2 models, but the lenses are the Hella TN4 units without the horizontal offset. The painted brass trim rings on many of the TN4 lights do not have the offset between the inner and outer circumferences, so the faces are flat. The light diffuser that shields the bulb in the TN4 lamps is what appears to be tin and is not chromed. The Hella fog light switch in the 1973-1974 model year Porsche 914 vehicles is identical to the switch used in the 1970-1972 Porsche 914 and 914/6 models with the exception of an amber insert with a slightly different graphic. Normal problems associated with both styles of the round Porsche 914 and 914/6 driving lights are lens wear & cracking from road debris, ring paint wear and chipping from same, housing rust and reflector dish rust.

P914 is currently offering a set of nicely refurbished Hella TN4 fog lights (with brass offset trim rings) for sale. Details are available in the SALES section.
