This is a photo showing my Bachmann observation car next to the coach. The coach has the original 2 incandescent bulbs lit by a 9-volt that comes in the car. The Observation car has a string of micro-LEDs run by 3 AA batteries that I installed today. Frankly, the 2 bulbs were pretty pathetic. You could barely see the cars were lit when running them at night.
