I was wondering if there were some typical things to check on this. My light in dim in my 2029 2-6-4 steam engine. I put a new light in, the socker seemed loose so I tightened it too. Now it seems dimmer. The light in my 1936 engine is much brighter and white.
What areas/things should I check to rectify this?
Thanks!
The 2029 is an O-27 loco. Lionel designed O-27 locos for a maximum voltage (eg. full speed) of 16 volts, while O locos were generally designed for 20 volts. Thus O-27 locos typically used a 14 v bulb (like a 53 or 363) for the headlight while O locos used a 18 v bulb (like a 1445). If you used the higher voltage bulb, it would explain the dimmer light. Also check that the socket is not bent in a way that the bulb filament is not centered behind the headlight lens. An electrical problem could be causing a high resistance in the bulb circuit, but this circuit is so simple that this is a very unlikely cause unless the problem is also causing slower operation of the motor as well.

If the light is reasonably constant then the problem is unlikely to be lose connections. I would tend to wonder what voltage bulb you have, as the same outline bulb is likely to be available in a number of voltages, typically 6,12,
16,(20),24 volts. It's just possible that the alloy chassis has oxidised where the bulb holder fits and has effectively created a diode that is halving the voltage, but unlikely.Regards, Greg.P.
Put a 14v in there and it's still dim. Not as dim as before but not bright white like the one in my 1936 steam engine :( I tested and I'm running 12v max on this engine.

Older engines had simply a bulb open & exposed to the front, the 2029 has a plastic "lens" through which light from the bulb must pass through, so it does not shine nearly as bright as a bare bulb.
