Mike and Harry Pyle are correct about the 50 watt halogens for lots on night use
. the current drain is about equal to the average output from your generator. I
would suggest the 12v 35/35 halogens as the best bet. They are still over 70%
brighter than the original bulbs with almost the same current drain.
By the way. I make the bulbs for Andrew Brock the Octagon Car Club
and Little British car Co. in Detroit www.lbcarco.com
