OK, I'll ask the stupid question. The "numberboard" lights appear to be some kind of blue halide light, while the headlight isn't. I've seen the BNSF use those for the past few years. Cars use blue (metal?) halide headlights. Big aircraft use them. I may have seen a diesel truck use them. Why aren't they used for locomotive headlights? (I figured the reason may be: 1) perhaps they're not as visible during the day, as 24-hour visibility is obviously critical for locomotive lights; 2) they perhaps burn out more frequently and require more frequent changing?). I've been curious on this for awhile.

The newer GEs are coming with LED numberboard lights.

Betting by the number of Lighting elements surrounding the number boards that they are not the Blue-HID as you are referring to but rather LED's. LED's use far less wattage to run for the light output not to mention the sheer cost of HID lighting, they are tremendously more expensive than a traditional Tungsten Filament lamp.
