With the use of selective compression, this lighthouse works on an O-gauge hi-rail layout.
The lighthouse measures 6" tall from its base, and including the scenery base it stands on, the overall height is 8". The width of the lighthouse at its base is 1.5". The max length & width of the base is 5.5" x 4".
The solar cell charges a 1.2V Ni-Cad battery that is accessible under the base. The light source is most likely and LED. When the solar cell is in darkness, the light atop the lighthouse illuminates. There is an ON - OFF switch on the bottom of the base.
It's an easy mod to bypass the solar cell, eliminate the battery and switch, and wire the lighthouse to an accessory circuit on the layout. The circuit board is readily accessible alongside of the battery.
