    Default What is it. DS Toggle switch

    Hello out there,
    This switch cam with a dashboard I picked up recently for my 1974 D Special.
    It operates as an either/or switch. Press it down and circuit A comes in. Press it up and circuit B comes in
    It will do duty as my wireless switch (there being no auxiliary position on the ignition switch)
    But does anyone know what it is really for??

    Parking light select. Left or right.

    I believe that there was a law in Europe at some stage (early 60's?) that required cars to be lit when parked at night and this minimised the current drain by only selecting the minimum required to be visible. Selectable because which side of the road you park is more of a guideline than a rule in some parts of the world.

    I could be wrong of course. I also seem to recall a simlar setup on Renault 4.

    Cheers, Pottsy.

    This switch is used to determine which side of the vehicle is to have parking lights when parked.
    Changed depending on which side of the street you are parked on in case you are in one way streets etc
    I believe they were not required here but part of design rules in Europe.

    Cheers

    Agree with this interpretation. Common European requirement - helpful with narrow roads/snowdrifts etc in the dark

    There are also other ways to do it - in one car I had (I think an Audi 80 ) one achieved the same effect by moving the indicator stalk to right or left position once ignition off

    One other quirk of such regulations can be seen in the external parking light switch on the rear mudguards of some 40's and 50's British cars. I had a Wolseley 6/80 with one and I think that some of the early Morries had them

    I think that is still a function with AUDI/VWs. I sometimes see cars parked in our town's main street (nose in angle) with the left park light on as the indicator has not self cancelled during parking.

    404 had this feature too - not wired up on Australian build cars but the information was in the wiring diagram.

    Correct - was required in the netherlands by law - parking light to be lit when parked outside of city more that 50 meters from a street light. The 60's model 2cv, dyane and id19 used a round switch with an arrow etched in it. Parking light (red back - clear front) located between front and back doors - close to roof line.

    Later models used indicator arm to activate parking lights...
