The ones I'm talking about have the screw-in base that goes right into the head-light socket.I have not yet but plan to. They look great. I will probably get mine from Evans Designs. They can be hooked up to
AC or DC, They include, built into the wires, resistors and all. I think they run around 3 bucks each. Hook up 2 wires
and bulbs should last a lifetime.

Hey Loren,The ones I'm talking about have the screw-in base that goes right into the head-light socket.
No need for any of this with Evan Designs. Get their 3mm warm white universal solid for $3.25. Cut out existing bulb, solder in new light, secure it in the headlight hole, and you're done. It will last for yearsLEDs run on a conventional engine is tricky. Voltage spikes will get to it. They do not like changing voltages. For a LED headlight I would go with a bridge of diodes and a capacitor. IF you have the room a DC output voltage regulator
Going the minimum with a resistor and one diode will eventually fail.
I use them also. They work very well and I have had no problems. It's nice to have all the light coming out the front and none leaking from the bottom of the locomotive.I use warm white for steam engines
and cool white for diesels
I use them all the time in the project engines I build up. They are available in 3 mm and 5 mm diameters and are high-intensity LEDs, very bright. They require 3 volts or less. Less is better. I use a 470 ohm resistor in series with the LED feeding it with 5 volts DC. You can find tons of these on eBay and they are very inexpensive.Anyone using LED bulbs for their head-lights?? The ones I've seen on ebay look "tall", and may not fit the tight space in flyer loco shells. I know I sometimes have trouble fitting the correct bulbs in the boiler shell... Thanks
Room can be a problem.. I was referring to the sockets that are attached to a boiler front. I've found that certain bulbs are too tall to fit into the front of the boiler shell once installed in the boiler face, the top of the bulb will hit the boiler shell, and the boiler face won't fit.Room is not a problem in S scale. Biggest problem is we use AC power for our trains.
