(W180): Dados técnicos de alteração/conversão da lâmpada de estacionamento para pisca

The fender-top parking lamps on my 1959 Mercedes-Benz Type 220S Ponton coupé were originally intended to illuminate one side of the car or the other when parked on crowded European streets at night. This practice is long since out of date (and such lamps were never used in this country). My coupe has a small toggle switch under the left side of the dash that can be clicked left or right to select the lamps on either side after the main light switch has been turned all the way counter-clockwise (one click left of the off position). Sedans with fender-top parking lamps have a similar setup. 

I've often thought that those useless lamps should be put to work somehow so I converted mine into blinking turn signals. It turned out to be simplicity itself.

First of all, it doesn't matter if you have juice to the parking lamps at present. What does matter is that the bulb is good and the parking lamp sockets are in good, clean shape and can carry current. Just follow the steps described with the pictures below and you'll have an extra turn signal blinker. 

I should mention here that, by plugging the wire to the lamp into the opposite end of the junction box, the parking lamps will light up along with the headlights rather than blinking. That's OK but hardly as useful as an extra blinker.
