Phil:
I made reflectors for my Williams engines. Basically, I glued aluminum foil onto a paper plate then cut out small rectangles that would fit inside the nose of the shell. Poke a hole in the middle of the reflector and push it down over the bulb then bend the top forward.
I’ve kept the homemade reflectors in my Willians engines even after converting them to series wiring. By converting to series, not only will the headlight burn brighter but, the engine will run much more smoothly. If you are interested in series wiring your Williams, do a search here on the forum or go to Bachmann’s website. There have been numerous threads over the years detailing the easy process to series wire a Williams.
