Hello all,
I hope this is the right subject i post at.
I have some questions about the MK 126, car alarm simulator:
I want to know how much vdc the system outputs to the red led? I tried to messure but its a quick pulse so i cant see a value 
Thanks
I think that is the same LED in this link.

So the LED needs 12 volts DC and flashes on it’s own.
Sry but your link doesnt work
Well the led in the set has a metall cover not plastic…
You say its flashing on its own so its a special led?
I thought for the flashing the capacicator c2 is responsible?
If the one you have is in a metal cover it’s not the same.
Sorry my mistake.
so one more question:
is it possible to change a unit in the curciut to have a permanent 12VDC output?
is it possible just to replace C2 by a wire for permanent output?
