4x 2-wire Red/Green Ground Signal – A pack of 4 x 2-lamp plug and play signals in 4mm scale (OO), supplied with NO control board.

The DCD-MS-RG.4 is a simple design 2-lamp ground signal that was first seen on a limited basis in the 1920’s in the UK, but it was very widely used internationally.

In addition to its world-wide use, it is also perhaps the perfect “indicator signal” for those with large storage or fiddle yards, giving a clear “Red/Green” indication of track access if used for this.

Use as add-on for Alpha Mimic control signal systems OR use independently if you wish. Please note: If used with other power sources, resistors MUST be added – a selection of these are INCLUDED with this 4-pack
