  I've had the Unity spotlight in use for a year already, but I want to get
it right so that on really dark nights in the Outback of wherever, I can use
it continously, without worry of an electrical fire or a dead battery. Used
with along  my two KC daylighters  and my euro pattern halogen headlamps, I
can really begin to  light things up..  Having that thin very strong beam
coming from the roof allow you a long 'throw'..

  One more idea I've had is to mount a 'masthead' strobe,
yacht-type... somewhere on the van as an 'intruder' chaser.  I think one of
those with a button or switch you could reach from your bunk would be good
for peace of mind...If someone comes around in the dark of night and starts
messing with the outside of the van while you are inside..you could just
touch off the strobe and probably startle the guy away.  That is if the dog
is too sleepy to eat the intruder or you are in an urban stealth
situation...
