Contrary to Larry's caution on the 100's , I have run them for now going on 200K miles in the Bosch Fixtures, with heavy wiring and relays. Absolutely no heat or melting problems.

I would recommend 80/100's versus the 55/65's. Buy the Osram or Narda bulbs. www.DanielSternLighting.com has them and the various electrical goodies.
The vacuum switch and panel came from Randy Steele at www.epsparts.com
Unsure of that website.
