Bachmann F40PH adding Blinking Strobes?

[Artieiii]

I would like to add dual blinking strobes on the roof of my Bachmann Spectrum F40PH NJ Transit engine like the prototype. I am using a Digitrax SDH164D.
1. How is this accomplished?
2. Do I need to find blinking LED's or will the Digitrax decoder be able to make the strobe effect with it's CV settings?
3. If it's the settings which CV's need to be adjusted?
4. How should they be wired...ie in series or in parallel?
Thanks in advance.

Ok each LED for the strobe will have to be wired seperate. Set one led/function to single pulse strobe and the other LED/Function to Double Pulse Strobe and you will have a prototypical flash pattern for the units.

I used a NEC DASR decoder to get the following result.

Wow that looks perfect to me! Great Job.
So you are using LED's wired to separate outputs on the decoder?
What size LED's I am guessing 3mm?
Any idea which CV's to change to get the single and double strobe effect with my Digitrax SDH164D?

It is nowhere in the documentation.
