Roof Marker Lights
 

My 2 roof marker lights on my F4 are a little rough and the gaskets are poor as well. What have you used as marker lights that still have an old look? Some of the NOS ones I have seen are a little crazy.

This is what I put on my F350 in 2018. I found them at the local auto parts store. I bought one to see how it would look and if it fit the curvature of the roof. It did and it looked good and looked vintage. I found the same clearance lights on eBay. I don't remember the name but do a search and you'll see a bunch of them.

I like those. I’ll have to dig.

This might help. I'm at my desktop and found a closeup in a file. I think it is Grote brand. And it looks like the number is 4533.

Thanks for the info!

If you are interested I have some intact spare original glass ones off my truck I think I have 3 spares.
Gaskets are not included as they don't exist anymore.

I don't believe roof clearance/marker lights were introduced until 1959 under the original part umber B9T-15442. These then can be traced through various part number schemes available on 59 through early 76 trucks.

B9T-15442-A
C1TF-15442-A
C1TB-15442-C
C1TZ-15442-A
C2TZ-15442-B
D0TZ-15442-A

ok so they aren't factory then, good to know.
