I'm going the same route with Misfire as I did with Warbird, Tapturn flasher unit:
http://www.autowindow.com/choose-module

I got the $99 unit which includes these features:
-LED compatibility
-3 - 6 blink Tap Signaling
-Arrival & Departure Lighting
-Directional Parking Lights
-User Programmable settings
-4 Hazard Patterns
-4 Selectable Strobe Modes
-Strobed Signaling option
-4 more Strobing Hazard patterns
-Strobed Remote Lock confirm

The Tapturn feature alone makes it worth it to me.
