Biktrix Ultra 1000 Middrive - Anyone Done Any Headlight/Taillight Upgrades?

[imdudesdad]

I'll just cut to the chase. The front and rear lights on the Biktrix Ultra (and Stunner X) suck. (It's a controller output issue). Has anyone upgraded the controller, or added a second controller/battery pack? I really just want one button to turn the lights on and off. Just curious.
