we had quite a few of those DS ones abandoned at my dads works, due to renting out a yard to the contractors building the Blythe Bridge Bypass. I used to raid the PJ996 batteries out of them, 2 in parallel. Behind the pinhole was a push-push table lamp switch. The bulb was a tubular MBC and it would only flash with the correct bulb rating in, due to the simple transistor flash circuit. The duration of the flash was extremely brief and the bulb had a fast-acting filament. Pleasant memories!
