The locomotive in the picture is the Series II conventional set from a number of years ago. The electronics were completely replaced with ERR command components, the Cruise Commander and RailSounds Commander.
The front class lights where there originally, but on the stock locomotive they're pretty dim. Stock they are lit by a single bulb that also illuminates the headlight. I replaced them all with individual direct illumination LED's. The tender doesn't have any lighting stock, so the markers and backup light were added. I also added an automatic cab light and Rule-17 LED headlight.
