Frank -

I'm using two 6 - LED fixtures manufactured by a company called Holly Solar.

The problem I wanted to solve was needing two independent reading lights for
the bottom bunk, plus have cargo lights for the back cargo area, plus have
lights so I could see into the back storage lockers at night.  To do all
these jobs, the lights had to have a swivel neck so I could point it where
needed.

I ended up using 2 "CLW-6 Cabin Light" fixtures wired to my auxillary
battery powered by a solar panel.  If my math is correct, they each consume
less than one watt!

Here's the dealer I bought them from, and his prices are good.  He also
sells these fixtures in 1 LED, 3 LED, and other configurations as needed.
The 1 and 3 LEDs don't have enough light to serve as cargo lights....just
barely enough for reading, IMO.

These lights aren't cheap; $41 each.  But they'll last without maintenence
(or bulbs) for the life of your Westy and beyond.   If you want a picture of
how I mounted them, let me know and I'll put a snapshot up on the web.

Happy motoring.
