Suggestions on installing lights

I am a member of a volunteer EMS service in my area. I have a dash light
wired in to the cig lighter on a 2002 T&C, and would like to install either
strobe lights (In the headlight and tail light) or sealed stobes (inside the
car behind the glass) and a siren. My question is would it be ok to wire it
in to the cig lighter or run a line from the battery? Also does anyone know
if the car has a battery shut off so the battery does not die?

Thanks
Toby

Thanks for the info, one other question. I remember you recommended a
replacement headlight bulb manufactured by sylvainia. Was it the
sliverstars?

Thanks

Not just "No", but HELL NO! Sylvania Silverstar is just another blue bulb
scam. The performance bulb in Sylvania's line is the Xtravision, in the
pink-and-black package.
