My first try at pixel hunting and coding (well, an easy one

First, and hopefully not last piece of the Hungarian set. I know, it's not a big bang, but I like it.
Any help is welcome...
Edit1:
Remark: since it's a beta, semaphores are light signals too.. maybe later time I will draw them, or someone else..
Edit2:
As You may not know by default:
- Normal signals: colored stripe on the pole has a break (ie. the red or yellow stripe has a white paint-on)
- PBS signals: colored stripe doesn't have break
(G)(R)(Y) - Standard signal (on Red-White-Red pole)
(R)(G) - Exit signal (on Red-White-Red pole)
(G)(Y) - Entrance signal (on Yellow-White-Yellow pole)
(W)(W)(G)(Y) - Combo signal (on Yellow-White-Yellow pole)
Key: (G) Green light (R) Red light (Y) Yellow light (W) Lunar white light
Ordered from top to bottom
Edit3:
just corrected a typo above in signal light colors
