A few of us were round a friend's house after a night out, when another of our number turned up carrying one of these lights (and, of course, completely drunk #-) ). Whilst deciding what to do next, we disassembled the whole light, and bypassed a couple of resistors with smaller one(greatly reducing the circuit resistance). This had the effect of reducing the period of the cycles; the maintenance lamp now did a passable strobe impression! So we took it out along the roads towards Stanstead Airport, which were completely dead at that time of night (3am). We left it in the middle of a dual carriageway, blinking away quietly to itself. It was visible (laterally) for about half a mile; vertically, it was almost invisible due to the Fresnel lens. Looked really cool. Just thought I'd let you know :-) -- ______ _________ /__ (_ \ Hertfordshire, England \_|avin __)allery \______________________ ...
