fog light knob different kinds

[bfrenz]

What is the difference in these two. Is the green one a VW knob, or did 914's have two different fog light knobs.

I think one is from a earlier car and the other is later? I know my 73 should have the green one, but it has the yellow

[scg]

Green = driving light
Orange = fog light

...maybe? symbols seem to say that to me...

[tracer]

scg is correct. There was a discussion on this topic last year sometime I remeber reading. I put the green on on my car since the amber one is so darn bright.

[chief914]

mine has a red one! It is a euro model.

[bowlsby]

Hey Chief show us a photo of the Euro one?

Like Tracer, I put the green one in due to the brightness of the amber. I found it way too distracting.

I also believe the symbol on the green center is for driving lights, amber for fogs. Since I re-wired the circuit for always on regardless of hi/low beam and replaced the fogs with driving lights, the green is appropriate.

I have one of each on mine though they are not yet connected to anything.

Being a fan of too much light, I'll install a set of yellow fogs and a set of white driving lights... each being over 5" diameter. I always thought one switch was for driving and one was for fog. Now if I could locate that red one someone mentioned, I would install a rear fog light too.

Responding to the questions about green and amber fog light symbol discs: the discs and the switches used on the 914 were sourced from the VW type 4. The two position (on/off) switch made by HELLA the metal body of which is replicated by the HELLA on their subsequent accessory switches.

It was listed for use with front fog lights, rear fog lights and heated rear window

411 959 621 (switch body)
111 941 515D (escutcheon)
411 953 245A (switch knob)
411 941 543C (green symbol disc - hrw)
411 941 543L (green symbol disc - fog lights)

The earliest fog light symbol discs were translucent dark green with two different symbols, later replaced by the opaque bright green disc again in two symbol versions These were diagrammatic representations of the lamp body plus horizontal bars and vertical line representing the fog and limited distance which was for the front lights. The second - for the rear lamp - had a vertical bar behind the representation of the lamp body. The later amber disc had just one symbol.

The translucent dark green discs dated from 1968/9 onwards (Germany having type approved rear fog lamps from 1966 onwards)

The bright green opaque discs date from the early 1970s and replaced by the amber in the mid-seventies.

A top tip in reducing the distraction of the illuminated disc at night is to replicate an insert VW used on some 411 hrw switches by cutting a circle of scale modellers black plastic card to the diameter of the outer edge of the symbol disc lip and punching a hole in its centre. The black disc should be placed behind the coloured symbol disc and then both inserted back into the rubber knob. Then when illuminated just the switch bulb just illuminates a coloured area the size of the punched hole.
