Brian:
You joined a thread about using 4511 sealed beams in the pancake housings. You had a system where you converted your old sealed beams to bulbs. I'd like to know more about it. Which reflector housing you use, etc. Your Private Message link does not work. Please respond. We can then email, telephone, or whatever.
Thanks. (My lights are still working fine thus far.)

Red,

Yes, I do have a method of rebuilding the sealed beam pancake lights to allow one to reuse the old lenses/reflectors. I will describe it here, I am also planning to put together a tech article with pictures on Farmall Cub Dot Com this spring when the weather warms up in the shop.

What I do if take the old lens and carefully pry it from the old reflector. Then unsolder the original bulb holder and remove it. Go to Autozone or the like and get a two prong metal bulb holder and solder it in. Also solder on a short bit of bare wire for the ground to the back somewhere. Then simply paint the reflector with silver paint, clean the old lens with 0000 steel wool and RTV the lens back on the modified reflector. I then crimp on a small bare ring terminal to ground the reflector to the housing. When you get done, it looks 95% factory. Only thing that isn't right is the missing screw terminal on the back of the housing.
 
What is your technique for removal of the guide lens from the housing/reflector? I experimented with a light with a bad housing body (had rust holes through the back) and found that I could pry the crimp off the lens by first grinding (thinning) the outer edge of the metal crimp.
I also tried using a reflector w/bulb socket from an IH (older) bulb type light. It would fit the pancake housing with a little grinding of the edge, but had a bent lip around the circumference which prevented it from seating to a proper depth for both the gasket and rim - together. I could put it together without a rubber gasket, but that would not be good for the long haul...... Thanks.

I simply work around the edge with a small screw driver carefully straightening the crimp out. Once I got the lens out, I go around the edge with needle nose pliers to further straighten out the edge.

No grinding is necessary. You could try using the older style reflectors, but will end up with the same results as I do, but waste an old reflector that you might need some day for another tractor. If I remember correctly, the light sockets at Autozone are like $2 or less.

When I get some pictures ready, I will be post them here as well. Enough are interested, I may do it early in the house.
