Looking to add an OEM style under hood lamp

[Kern Dog]

I want to add a lamp under the hood of my 70 Charger. There are times where it is dark and holding a flashlight isn't practical. I recall seeing some car awhile ago that had a detachable underhood light with a cord that allowed you to position the light where you needed it. Does anyone have any additional info on this or something like it?

My 96 Suburban has one on a cord that has a magnet on it. You can unwind it, stick it to the metal and then wind it back up when your done. Like this one
