Main light for Twelve Sports Tourer

Post by ThomasMoRo » Mon Jun 03, 2024 1:41 pm

My Twelve Sports Tourer JPO 848 is in Germany now.

We now have to clear the next hurdle, the German TÜV (Technical Inspection Association), in order to be allowed to drive the vehicle on German roads.

There could be a problem with the main headlights; they don't have high beam, only low beam. We will probably have to retrofit the high beam.

It would be good to know which types of headlights are fitted. Can you perhaps recognise this from the photos?

Regards
Thomas

Hello Tomas,

The reflectors are younger than the car. If you remove the rim, glass and reflector, look at the bulb holder. The original bulbs fitted had only 1 filament and the beam was switched from high to low (we call that dipping the headlamps in the UK) by switching the off side (drivers side) headlamp off
and powering up a solenoid that tipped the other reflector down. At the same time, the pass lamp that was aimed at the passenger side kerb was switched on.
This dipping system was discontinued in the UK in the 1950's and 2 filament headlamp bulbs were then mandatory.

Hope that this helps
Mike
