The last pair of lights are Guide 682-C's with what looks to be the earliest version of the top light. Cool. The middle pair are Ford parts, 1938-39 truck I believe, with the lighted bases.
As for that first set, I know '36 Plymouth had those ribbed little trims on the stands like that. Looks like they have an aftermarket sealed beam kit in them and some add-on turn signals too.
The lights with the oval lens in the stands (parklamps) are Ford 1 ton and COE trucks 1940-47. YES, those lenses in the stands are the same as interior door post courtesy lamp lenses on the Ford passenger cars.
Those '40-'41 Ford big truck and '40-'47 cabover lights and stands are a bolt on swap for '38-'39 trucks.
There is NOWHERE else on Earth that sits on this much combined knowledge! Thanks for your help, one and all.
Yeah my bad mate, for some reason i couldn't see the second set the last time i viewed the thread. The last ones are the Guides i was talking to you about.
