Bell1220 Posted April 22, 2012 Share Posted April 22, 2012 I have a bunch of these new unopened in a box GE All Glass Sealed Beam Lamps. The box reads: 4578 60W 28V, and on the bottom of the box it also has MCG461CE. On the back of the lamp it reads: 60W 24V GE4578 CIM Flood 10-0. Also USA and 217. (Why the box says 28V and the lamp says 24V....????) The lamp is 6" in diameter. I am pretty sure these are automotive headlamps....but, for what vehicles could these be for? What kind of value could these have? We have had them since new anywhere from 15 to 30 years - but no longer have any info on them.Please see photos below: Link to comment Share on other sites More sharing options...
Dave Mellor NJ Posted April 23, 2012 Share Posted April 23, 2012 The only vehicles I know that use 24 volts are Korean era military. I was just looking at a friend's M38A1 jeep which was 24 volt but the generator said 28 volts. look at some pics of the larger trucks, maybe you'll recognize that lamp.

Layden B Posted April 23, 2012 Share Posted April 23, 2012 There are/were other applications for sealed beam lamps, battery powered standby emergency lighting for buildings comes to mind. Link to comment Share on other sites More sharing options...
ply33 Posted April 23, 2012 Share Posted April 23, 2012 There are/were other applications for sealed beam lamps, battery powered standby emergency lighting for buildings comes to mind.And aircraft too. I'll look up that lamp number in my 1970 GE lamp guide this evening and see if it is listed, if so they usually give the typical application.
