Flasher circuit using a BD679

[ozspeedway]

Hi all

I am trying to implement EddyCurrent's flasher circuit but am having issues with it. He uses a System1 V2 BOB and I am using a PMDX 126. In a PM EC explained he used the BD679 as follows:

Pin14 from the BOB connects to the base of the BD679 via a 2.2k ohm resistor. The emitter is connected to 24v negative and the collector is connected to one side of a "lamp". The other side of the lamp is connected to 24v positive. The flashing is controlled by a brain supplied by EC.

Now, I built this little circuit using a 24v LED as the lamp and it just glows in a low light and does not flash at all. I have PM'd EC asking what his "lamp" was but at this point he has not replied. I am now suspecting the "lamp" may be just that, a light bulb and not an LED. My LED is a true 24v LED in a pushbutton size package.

Can anyone see what I might need to use the 24V LED in a circuit such as this AND have it flash as required from the brain?

Any help would be appreciated.

Cheers
