CSX premier ditch light out 20-2983-1

Willygee, on MTH website click on service then under repair links, click on order parts. Enter your 20- number. Scroll down to bulbs. From what I see there, they only show grain of wheat 2.3 mm 6 volt and 3 mm 1.5 volt. It's probably the 2.3 mm.

If PS-2 bulb 6V; if PS-3 LED.  Some PS-3 use SMD Type LED.  G

Thank you DZ and GGG...is it just a bulb or whole housing assy?

The bulbs insert up threw the bottom. I did find it strange that they list a 2.3 mm 6 volt grain of wheat under that engine being it is a 3 volt board. I don't know if 3 mm will fit. GGG do they make the 2.3 mm in 1.5 volt?

I have a bunch of 2mm natural white led's...can they be used with appropriate resistors i wonder?

Willygee.....I had one go out on a tunnel motor, what happened is the bulb dropped down in the hole it fits into. It was still working just couldn't see it.

I will have my man check it.

yes

Yes they have a small diameter bulb for some applications.  Yes just bulb.  3V is bulb, PS-3 is not 3V  it is PS-2 so bulb.  Yes LED will work, just use a resistor to regulate current down based on a 6V PWM voltage.  As an example MTH use 150 ohms for parallel marker LED on a 6V CV board.  I have used 150 and also 220 on series wired markers for upgrades.  So adjust resistor to your brightness liking.

thank you work in progress... easier than I thought.

I have done markers,headlights and number boards before..some in parallel some in series.

I always start with a high resistor and work my way done to scale brightness.

 It has always been those springs acting up for me. I haven't lost a bulb yet!

The ditch lights in my three engines come from the board, not the springs.
