VR light signals come in several different types. This up automatic at Sunshine is a standard "Style R" type that was the last light type signal used until the introduction of "searchlight" signals. This automatic shows only normal speed aspects:Clear Normal Speed, Normal Speed Warning (shown), and of course Stop |

This "style R" approaching Frankston, only has two top lights (yellow and red) which means it cannot show green over red. This is because the next signal, Frankston's home arrival, only shows medium speed aspects, so the best aspect this automatic can show is yellow over green, reduce to medium speed.
