@gunrunnerjohn posted: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?
