I just cleaned these up the other day, still need to get a few dents out and rechrome the reflectors. My main question is, does anyone sell glass for these or am I going to have to make something work? Sorry for the grainy pics...
You can even update to halogen... http://macsautoparts.com/search.asp?t=ss&c=222&ss=headlight&year=0&sb=4 I probly have one lens, but for the price I would go all new.
Lang's, Mac's, etc- like barry said, you can also update with halogen. If you want original, you can find a bunch on espay, but most T headlight glass would "purple"- you want to find a pair that match.
One suggestion is to weld in housings from a 70s era car which uses round headlights. The original T outer trim rings hide the inner rings/mounts and looks clean.
If you want clear glass, I had some made at a local glass shop. If you want the fluted Ford "H" lenses, all of the Model T parts suppliers have them at a reasonable price.
