Constant Lighting, Forward/Reverse by Miniatronics Corp

I've used the Miniatronics constant lighting units in my locomotives for years and am very happy with them. I think they smooth out the performance of Athearn blue-box engines and the light intensity is terrific. I do not use lenses with the bulbs so they're at maximum brightness. If you're careful about installing the bulbs it's hard to tell there are no lenses. The units are easy to install and basic soldering skills are the only requirements. I highly recommend these units to make your analog locomotives operate better and look more realistic.
