ABC is right; it's easy to do your own lights. However, the incandescent lights use a lot of current which won't be available for your locos. They also make a lot of undesirable heat. Try LEDs. They use very little current and generate almost no heat. You can get the parts from ebay and instructions on the web. All you need is the LEDs, some resistors and a magnetic reed switch. You can even use batteries if you want. I don't like the battery unit (like Easy-Peasey) because the batteries are expensive. I suppose you could use AA or AAA batteries instead of the button batteries the E-Ps use.
