I noticed the same problem - for now I've just removed the standard light bulb and intend to use the "Brass tube and LED" method as described above. I also have to sort out most of my Athearn hood units with a similar system - the only ones I'm happy with the lighting on are my SD9, PA and SW7s. Thanks to the high-nose on the SD9 there is little or no glow in the cab at sensible speeds, while the others have a plastic moulding around the bulb to prevent this problem. <br /> <br />One question however: Can anyone explain what rating LED (and diode, for directional lighting as apparently LED's don't like having power put through them "the wrong way") I will need to do this - my knowledge of electronics is limited to being able to wire layout electrics using off-the-shelf components! I've seen cheap bulk-packs of LEDs from Maplin (electronics supplier over here) but don't know if they would be suitable.
