Triple Head Signal Mast on a Signal Bridge...

So in the last week I have begun installing the new signal head masts.  To start I have decided to incorporate more signal bridges on the layout than just a standalone mast.

As in the previous posts I have used the IHC Signal Bridge kit for this.

First step of the Triple Head installation was to convert a Tomar - H876sl into a Signal Bridge Mast.  This involved cutting off the bottom section & base.

The next stage was to feed the twelve (12) wires into the mast for the three (3) searchlight heads.  Luckily the bottom head didn't need to be fed through with the middle & upper head, although all twelve do fit into the mast.

Once the wires were threaded through it was onto soldering on the wires for the LED's, this involves checking each LED as it is finished.

When the LED is fitted I add a clear domed light pipe to act as the sense and hide the physical LED.  It also helps spread the light evenly out through the whole aspect opening.

When the three heads are connected and installed it was time to install the mast onto the signal bridge.  This was fairly straight forward actually and surprised me how well it looked when completed, the mast is actually secured to the bridge by black wrapping wire and is quite sturdy.

As you can see the aspect color from these RRCirKits LED's are superb!  Once the signal bridge is painted and weathered the wires will virtually disappear.

Here is a short video showing the signal aspects programmed for the triple head...

  1. Hi Jason. I'm red-green colour-blind, and usually have problems with signals. But I had no problems with these LEDs. They're a great choice, IMO.
