I did, but knew I'd be the fool to ask (right?). Well, it was asked by someone on a German FB Trabant page and I just figured to follow and get my answer. It's this thing: It's a 6v or 12v accessory port (almost like a cigarette lighter). So I dug around and found that the most common accessory is the "handlampe". I found a bunch of them on eBay.de and just had to have one. Uses the very common 1156 type bulb and has 5 meters of cable (to allow full access around the outside of the car in the dark?). I just love the concept, on the side of the road looking around your car in the dark with the light output of a 21 watt bulb, beautiful. Here it is: I got it brand new, still in the original packing with the purchase receipt dated 6/89. Even has the "Narva" DDR bulb still in the box. I'm almost scared to plug it in, not sure I ever will. But it will make for another great story to tell at car shows!
