Buckpuck as 2 stage w/ strobe

Here's my plan for my motorcycle. 2 T-bin Lux3's in the stock housing for brake/tail lights. I see the Buckpuck you can vary the output current and also run in a strobe function. My initial plan was to run the current control pin via a relay to supply ~500 mA constantly, with 1000 mA when the brake circuit is active. But.

I've always wanted to put a very short strobe on the brake function. Several of the local PD's are using these on their bikes. When the bike hits the breaks you get a VERY fast strobe for 1/2-1 second, then just normal bright brake light.

Does anyone have any ideas on how to integrate all this? or even leads to the circuits I need to research?
Thanks in advance everyone,

^^^ Has anyone used the Buckpucks before? From the lack of information I'm finding the stobe is out for now. But I still want to 2 stage it. Is the buckpuck like the fatman that needs a pot, and will short if the control is removed?
