This fabulous little gadget brings action and animation to any layout. Powerful randomly flashing red LEDs produce amazing flickering fire effects, used in a diorama, working forge, campfire or locomotive fire box on your railway. Can also be used by wargamers to simulate burning buildings, tanks, hits on entrenchments etc. Place one on some crumpled foil inside that farmhouse you just mortared and watch the inferno! Placed behind battle table horizon, looks like distant artillery barrage. Brilliant for night battle in low light conditions.The unit is less than an inch long so it is suitable for any scale. No wiring required, runs off a watch battery(installed) A powerful magnet on the base allows unit to be attached to anysurface. Even clothing.( Be the centre of attention when you're out clubbing). Try it with the light out, you'll be amazed. I've sold a fair number of these and all buyers have been pleased with their purchase. Don't take my word for it, check out my feedback and my other items!
