The problem with lighting using straight DC is that the bulb brightness is directly tied to the input voltage to the track & loco. When the throttle is low, the voltage is low and the bulb is dim. There are constant voltage circuits available to correct this. They use low voltage bulbs and some sort of voltage regulator to maintain the low output voltage to the bulb even when the throttle is at a higher level. I've seen articles in the model magazines over the years on these circuits. If you're inclined to make your own, you might want to research thru the magazine article index search at- [url]http://index.mrmag.com/[/url] I'm not sure if there are still commercially available circuits out there. Try a Googhle search. Of course, with DCC, you get the constant brightness lighting automatically. Doug
