Now I have used various JMR Vader Signals which consisted of anywhere from 1 to 3 heads. Each head has 3 lights. However, I noticed that I also have the option of using a JMR signal that has 3 heads - but only 1 of them has 3 lights on 1 head. The other 2 heads have just 1 light each. What's the meaning of that design? For example: 2 headed signal: Top head (1 light), bottom head (3 lights). Another example: 3 headed signal: Top and middle heads (1 light each) and the bottom head (3 lights). I noticed that the single lighted heads are red but turn off if I throw the switch to go to the siding or diverge to another line. What's up with that? Are those JMR Vader Single Light Heads only meant to be red only? Where can they be used exactly or roughly?
