I have a 1975 911s that I backdated to be a long hood.

I installed H4 headlights. High and low beams work, emergency flasher works, turn signal indicators work. However, when you pull back on the left hand stalk -- the one that exits to the left of the steering wheel clam shell cover, to flash your lights to say hi to a fellow Porsche driver they don't flash unless you have the headlights on. I thought the headlights would flash, with ignition on or engine running, w the lights in the off position????

Can someone enlighten me?

Is my car capable of flashing its headlights with the engine on or ignition in the on position but the headlight switch in the off postion?

If so, any idea why mine aren't flashing?

Thanks
