The long-lasting red micro-LED used is adoptable to either scale and produces a bright red flash. The board is powered by a common watch cell battery and the kit includes a tiny On/Off switch to save power.
All components are small enough to easily fit in a standard HO or N scale box car and with some imagination, could be instaled in hoppers or other kinds of cars. The board itself is only ½” x ½” in size. The battery holder is 1” x ½”.
Red micro-LED lasts thousands of hours
Kit is easy to assemble and install
