Joined: 05/12/2008(UTC) Posts: 1,683 Location: Crozet, Virginia		I am looking for an LED replacement for the bulb shown below. It does not have a screw base but just two wires. It is for an old 3356 BR 103 which I am updating and I would like to change the lighting to LEDs. I have seen LED replacement bulbs for the screw base type but not for these. The Märklin manual that came with the loco lists the original bulb as a 60010 but that is one with a screw base, so I am not sure what bulb I would need if I do decide to stick with incandescents. Has anyone found a direct replacement or am I going to have to get creative to make this upgrade? Thanks!

If it is supplying AC/digital power to the light you will need to insert a diode. The resistor (and diode) can be to the left of the mounting, well away from the light itself, wherever you have room. Since an LED will not likely need replacing your modification need not maintain the plugability of the light.

Since an LED will not likely need replacing your modification need not maintain the plugability of the light. I know I need a resistor for the LEDs - what level of resistance do you recommend? It it not plugable now, so no worries there. I am installing a new mSD3 decoder, so it is not putting out any AC. I will need an array of LEDs though, since this bulb needs to shine in at least two directions for the headlights to work properly. That is something an old incandescent bulb has over any LED. Thanks for the input!

They should give me the info that I need to figure this out. I need to have light output upward toward the cab area and the top headlight and to the front and down for the light guide leading to the two lower headlights. That is something that you just get for free with an old fashioned incandescent. None of it is rocket science but it might wait until a little later, after I get the loco back up and running with its new "Hohenstaufen" coaches before I decide what to do about the lights. Thanks again for the input.
