I managed to burn out the tender light on my Bman Connie. Is it possible to change the bulb.
I can’t figure out how to open it, it appears to be fused into one piece. What’s the trick?

The light is an LED, so if it burned out, I’d probably look to trace the wiring back to see if there was something weird that happened that casued it to do so. Possible that it’s just a loose wire on a plug.
That being said, the headlight itself is just a press-fit kind of thing. You can remove the headlight by gently prying up the “legs” that are on it from the base. They just clip in. Once you’ve got that out, look on the underside where the wires come out, and take a small flat-head screwdriver, insert it into the hole, and gently press forward. The lens will pop out, followed by the reflector. From there, you can remove the LED to replace it.
While you’re at it, replace it with a warm white LED instead of the orange one that came stock. It looks worlds better.
Later,

Thanks Kevin. That’s exactly what I needed to know

If you expect a DC positive wire to be red and the negative black, be aware most Bachmann headlights and tender lights are wired the opposite way. Not really helpful when you are dealing with polarity sensitive devices like LEDs.
I dunno, maybe it’s the new holes move generation that have changed things around. 
Basic rule of wiring in large scale, don’t trust colors, trust your voltmeter!
The real fun begins when you find red wire painted black!

If I remember correctly, the diode for the tender lamp is on the circuit board in the back of the loco (with the sound switch and recepticle).

The loss of the LED is probably not anything else but the LED.
If it worked, the current limiting resistor is there (and don’t lose it…it may be in the wiring at the LED or very close too it).
Colours, yes, you never know with PRC production. Example: Early Shays. Seen red and black wires to motors, some red on one side, black the other, both ends. Some swapped at the ends. Some all red, some all black, some black ones you realize are red wires painted black and the paint falls off in your hands.
Current limiting resistors are 500 ohm or 1k ohm, and it varies. Depends on what was the cheapest for the factory to buy in quantity. Seen both, either is fine for the LED and the maximum voltage of our trains.
Remember, cheapest. Save a penny. LED’s can and do have widely varying quality. Cheap ones often go off like a flashbulb. All the LEDs on my PRC engines get yanked almost first thing and replaced with incandescents. Brightness and colour. Important outside in the dark.
