Strictly my opinion only- I don’t follow the market on stuff like that but they typically seem over priced. I think I bought my first car magazine around 1959 or so and not once did I see any Electroline tail or headlights BITD.
I can't say I've ever seen Electroline taillights used in old magazines either. But the guys with Electroline headlights sure seem to like to pay well for the taillights today. I've found a few at swaps over the years and always got good money reselling them. I wouldn't use them though.
These came with my coupe. Not really looking to sell them, just learn a little more about them. I’ve never seen them before.
Electro line made a bunch of different lights taillights like you have truck clearance lights marker lights and headlights. They were a aftermarket company that made stuff for fire trucks and commercial truck industry. Some of the stuff is cool and art deco look
