So here is the story. A friend on mine said that his Grandfather has these two lights. When he passed away they went to his Dad. The he passed away and my friend got them. He was going to throw them away and asked me if I wanted them. So what do you think they go on? I know one is a tail light and one is a side light.

the side light will work on 1910-11 overlands & others. charley

The black tail light fits a Model T from about 1915 on with magneto headlights. most of the later cars after 1919 came with starter and battery and used electric tail lights. But the low end still had magneto lights and no starter.

That particular tail light does not have the ring of ventilation holes at the base of the chimney, nor the round reflector inside. This particular black tail light is 1917 or later.

So the brass one is not for a Model T.

no it is not.i have a few overlands i could put it on.you figure out what you want for it.i would be interested. charley

So this is what I'd like to do. I got these for free. I can't use these on my 1926 T so I would like to sell them and then give the money to the Model T museum. I have no Idea what they are worth. So what ever I can get for them goes to the museum. Not sure if this should go to the classified side now or not. Please make me an offer. I know some have posted that they don't like when people say "Make an offer" but I'm a new to T guy (2years) and I don't know what they should sell for.

The black light is missing the top cap.

you could go to e-bay completed items and look them up. charley

OK I was contacted by a member for the black one and sent Charley P MSG for the brass one. If you guys like the prices let me know. Like I said the money is going to the Model T museum.

robert, i want the light. i just got the e-mail back i sent on i think on sunday. did you get the pm i sent? charley
