Locomotive headlight

[MF-]

Real-world locomotives have a big&bright headlight. (not sure how narrow cone they make, though)

I believe that the one found in Factorio should have one as well.
It's quite weird to that the main character has to use his flashlight.

It's a small thing, but I agree. The locomotive headlight could even be brighter than the flashlight.
