I have the same model in C&O, the cab light is incandescent. It's bright enough for me, but I don't like a sunrise out of the cab anyway. FWIW, I added an LED headlight with Rule-17 lighting to mine, it came when I upgraded the smoke with the Super-Chuffer. One major issue with those models is the smoke doesn't run at idle, but the heater stays on. If you stop for any length of time, it's cooking the wick as you sit there. So, I fixed that.
