Ed,

I am a sort of LED light fanatic..  Guess vanagon campers aren't my only
affliction

Anyways.. They last a REALLY LONG TIME on decent batteries.. 
I carry a small AA&AAA battery charger in the glovebox, 
wired into a remote cig plug taped into the cig plug wires
With ALWAYS having charged batts in the glovebox, it is really no
inconvience for the rare time one dies out.
Sure a little more initial investment, but the rechargeables are getting
cheaper. 
And I REALLY DIDN'T want to run dozens of tiny supply wires all over my
van, 
I have a large enough AUX harness in my inverter, and remote lighting
system as it is. 

I'm now in process of adding LED Clearance and rear visibility lights to
my camper as I find myself on dark roads in unknown terrain with rain,
mist, fog, snow.. 
And value my life and westy too much for someone who couldn't see the
TINY stock tailights way low on the body.

That's just my $.02 hope it's helped shed some light on things.

I would like to add some interior lighting to my '85 Westy. I have found

them off of 12 volts.=20

Is there an easy way to run 4.5 or 6 volt LEDs on 12 volts? Some sort of

resistor inline? These lights are inexpensive as opposed to ones I've =

cost.=20

What would happen if I ran them on 12 volts instead of 4.5 or 6?

Can anyone point me to a good web site which explains these questions? =
I've found some LED sites, but none that answer my questions.

Thanks,
