Most vendors sell a dual filament lamp and socket assembly that they list as a turn signal conversion for the stock tail light. Will these assemblies also work as a tail light/turn signal/brake light assembly since they have the dual filament?
Yes. With a 7-wire controller, the brake and turn signal uses the same bulb filament.
Yes, if you have your car set up or if you purchase or build the set that uses the brake lights as the turn signals -- those bulbs will work. Note that would be similar Lang’s 7 wire kit part number T-SIGN-7 that uses the cars brake lights for the flashing signal many USA cars from the 1960s & 1970 did it that way. But NOT their T-SIGN-4 which does NOT use the brake light filament. Remember to use the correct voltage for the way your T is set up. Stock batter T was 6 volt battery operated, but several owners have converted them to a higher voltage. Just purchase the bulbs to match the voltage on your car.
You can also use the T-SIGN-4 style – but you will need different bulbs and probably lights for the brake and signal lights. There isn’t a right or wrong way – just how do you want to do it on your T so you are more visible. At: http://www.mtfca.com/discus/messages/50893/79763.html Peter posted a nice link to an LED turn signal kit that was advertised for use on the 1928-1931 Model A Fords at: http://www.logolites.com/led/turn/signals/model-t.htm Note they show them mounted on what I think is a 926-27 Model T. .

that T-SIGN-7 is deivered with a 12V flasher unit. Will it work with a 6V flasher unit?
I called Lang's and Steve kindly checked the instructions for the T-SIGN-7. He said you can use it on 6 volts by switching to a 6 volt flasher unit. But, the instructions say the 12 volt indicator lights on the actual switch will be dimmer than if you were running it on 12 volts.
Hap again – So when you look down at the switch the blinking light that says you are signaling left or right will be dimmer. But the turn signals out front and out back will work normally. Also in the USA there are still many cars and trucks that have the brake and turn signal lights use the same bulb filament. In Europe many of the cars I remember had a different bulb for the brake and turn signal. If you are thinking about ordering one of the kits from a USA suppliers – be sure to obtain the correct 6 volt flasher at the same time, if it is not already included. The postage to Demark would probably be about the same and you would know the parts would fit. Note most of the suppliers offer both 6 volt and 12 volt version of most turn signal kits/parts. There are lots of choices – and there may even be a solution available locally there in Denmark.
I hope that answers your question.
