Love using the lights. I have those same lights in my project bin for use as an exhaust lighting for a power plant. I'm also using the white two LED lights on a customized attack vehicle I'm working on. The use of the UV in a night scene never occured to me and I'm looking forward to duplicating your effect in some of my night scenes. By the way, the Bailey bridge rocks!!! In scale is the bridge a one lane or two lane?
