Lights with Relay

I purchased three of these and one of another light, same company, same three light indicator. I like these, very much, but they are (to me) a lot of work to install. I had them up, but took them down to put somewhere else on the layout. You just have to keep in mind, if they are no where near your switch for them, its going to be a lot (a lot) of wire. I used to use them as block signals to mark lines as available, partially available, and permanent danger. I am going to place them at the entrance to my yard to mark lines going out of the yard and going to use automatic block signals to mark trains coming into the yard. I am sorry if I strayed about during this review. But they are worth $12.00 if you are into wiring. And you need to cut a base for the switch.
