Here is a pretty nice original 7- inch T3 Headlight for 1968, 69, 70, 71, Camaro and Nova with single Headlight per side. This is the later version T3 with vertical lines in the triangle, and think I'm pretty close to the years. As you can see in pictures it works good on high and low beams like it should. Numbers on back just below prongs are 150 013, on front above 12-v and the bigger 2 is F 6 3. Being electrical it is not guaranteed and please make sure it works for your application. I guess that's it, ask if you have any questions. Thanks
