We still have the grey plastic front & back Eveready (spelling?) lamps we bought for my wife's bike in the UK in the 1970s - see http://tinyurl.com/
I think there were similar lamps sold in the USA by Berec?
They took two D cells and the rear was simple, rectangular & boxy thing with a clamp to bolt it onto the (right) seat-stay - we ride & drive on the left, remember!
The front slid/clipped onto the usual British front lamp bracket - be that on the (right) fork-leg or the stem/headset.
