Driver for Strobe / Blinking Light

A search found a number of results asking about removing the strobe from a variety of drivers. I want to have a driver that would be strobe only. Ideally it would have maybe two or three brightness levels and possibly a choice of two blink speeds or one of those “police” strobe patterns. It would not need any normal on modes.

I have wanted to try my hand at driver programming, have bought the clips, etc but have not even put it all together yet. I realize that may be necessary. Anyhow any ideas on if there is something out there I have not found? Ideas on what path to follow?
