I am wondering how much this is worth. It is a whelen with two blue alternate flashing on the corners and a white 360 strobe in the center. it has two separate plugs
I can't tell from the pics, but a Whelen crossbar usually goes for at least $300, but it can be significantly more. A lot of it has to do with what base bar is used and if it is factory wired/built or pieced together. Another factor is which beacons are used and if they are original. This one has super strobes which, if original, date it to the 1980s This is a later bar, they were discontinued in the early 1990s and they sold the pieces separately for a few years. If you pm, post, or email some more pic (ram4elightbars@gmail.com) I can narrow things down more and make a real offer.
