Well after over a decade of operation, the lights which illuminate the number boards on my Lionel Big Boy (6-11126) recently burned out. Looked on Lionel's website and replacement bulbs (6101104302)  are out of stock. If anyone knows an alternative replacement for these that would a great help!

Peter, are you sure you haven’t accidentally turn them off?   Of course that would be too easy a fix.  It seems that 8 volt grain of rice bulb are the same as hen’s teeth.  How about prewired SMD LEDs?  They are smaller than the grain of rice bulb.  You can get 25 for $10 at Amazon.  You will need a resistor and a diode to knock 8 volts down to 3 volts.  There should be enough room in the smoke box to fit them.

I am not an expert on this, hopefully, someone who knows more can give you some specifics for the resistor size and diode.

These are the LEDs I got for the number boards https://www.amazon.com/dp/B07F...oding=UTF8&psc=1

pretty sure I used 0603 size but can’t remember for sure

I also put them in the headlight housing with a LED head light when I added GRJ’s Super Chuffer with Rule 17 lighting. I wired 2 LEDs in series and used 1/2 wave dc from the track with a current limiting resistor can’t remember what size I just kept adjusting it until I liked the brightness

For many uses for the SMD LED's, I use the 3528 size LED's.  I put them in the wedge headlights for articulated steam, they work really well and light the number boards on the side of the light fixture.  I solder my fine wire to them and then use Liquid Tape to insulate it.  I stick the LED to the rear of the light housing with CA adhesive.  In order to do the mods, I remove the number boards and headlight lens, then I can easily clamp the LED down and glue it.  This is an option I add for Super-Chuffer installations that allows you to use the Rule-17 lighting feature.

I got a set of EDGELC LEDs recommended earlier in this thread and they're rated for 3 volts. Seems running these at 18 volts would be way too much power.

John do you add a resistor? I got a set of the EDGELC LEDs recommended earlier in this thread and they're rated for 3 volts. Seems running these at 18 volts would be way too much power for the them. What would be a recommended resistor to use?
