THis has always been a challenger here. For the overhead console in a Gran Coupe or SE Challenger, the light was like the one you have on the right. The lens has ribbs over it & a flip switch. The switch is to be located on the front of the console. When you install the light, connect the wire harness to the red & yeloow connector of course, BUT you have to take the small gray wire, which is a ground for the dome light, & connect that ternimal to the dome light frame work. There is a tab for that & it has a small hole in it & this terminal stands straight up, underside of the light near the rear part of the light. Look close, you WILL see it. If you dont connect this terminal, the light will not work. Now, I know some Polaras & Furys from 1970-1974 have this same dome light & most people advertise them on eBay as to have found them in a Challenger overhead console or Gran Coupe. Thats all fine & dandy, get these lights where they are needed. If you have a decent light, don't EVER remove the lens for the whole unit, you can crack the ba$tard & it will never fit into place like it should. The bulb fo rhtis light has been out of stock & the best way to replace the lightbulb is this way: Remove the light as an assembly, turn it underside up & pull tabs away from the light bulb socket areas lsightly & pull it outwards & be care ful not to wreak the flip tab, gently remove the socket. Push bulb out & replace with new bulb. Installl in the reverse order above here, just make sure that the flip switch tab is through the cover plate & not under it or you'll bust it off. They are a royal pain to find another tab cover flip. I'm not going on about these lights, but Im giving whoever has NOT replaced a bulb here lesson 101 how to do this woith out removing the lens. I have a box full of of these domelights (mainly just parts) of busted lights from C-bodys over the last 20 years & its a pain to find a complete one. I hope this helps you out some!
