My truck has the later Twilight (Depressed type). Is it the wiring inside that is bad . Sockets and wiring new are available . The Filling Station is one that sells or other Chevy vendors early 30's too . 

The 30-U Plymouth had Depress beam headlights with painted buckets and chrome bezel.  They are shaped like Model A headlights.  I believe '29 Plymouth is the same except they have a chrome bucket and bezel.  I actually have the correct headlights on my car but the internal parts are toast.

What kind of headlights you looking for ? Only found few trinkets myself .Was looking to pic up whole rearend to get my truck better ratio .Vendor never responded to ask to bring , but was there with everything but .. Rrrr.

Searched in vain for headlights for my 30-U but the weather was great and I found some good buys for my other cars.  Early Plymouth stuff just doesn't seem to make it to Hershey the way it once did.  Hope others were more successful than I was. 

I found the same issue with pressure style switch. so I just converted to a on/off switch. working off the brake pedal.

It's Desoto 1928-1929

I have been looking for a couple of them for 2 years. I have the spring & hook parts but one of my brackets has been replaced by one that doesn't let the hood close right and another is in pretty bad shape. I may attempt to make some one of these days. If you find a source let me know.
