Thanks for the reply.  I've been on Amazon searching.  I did see this one last night.  But look at picture #2.  That looks like a 1.8mm with the large ring.  The first pic is definitely a different bulb.  Maybe 5mm?

I think buying stuff like this on Amazon is a crap shoot.  As you say, the second picture tells the tale, it's not what you're looking for.  FWIW, that is a very common format for 1.8mm LED's.

Couldn't you just shave off the plastic flange with a small utility knife. It's a 30 second job at most.

No, the first picture is a 3mm LED, and they already come in flangeless if you so choose.  What he needs is a 2mm maximum diameter LED.  The second picture that I posted above can not be shaved as the wide part actually has the LED chip in it.

Why not check with OGR Forum Sponsor, Evan Designs? They will have what you need.

I looked there and  all the 1.8 had that square base. Maybe call them.

I don't think so in this specific case Rich.  This is what Evan's offers.

He's looking for a specific sized LED that actually is out of production.

Ron, you could buy a harness from Lionel and use those.  These are 2mm LED's and should fit into the fixture on your engine.  Here's a couple of choices that are in stock at Lionel.  You might have to do a little wiring to make them match the MTH harness, but at least you can get something that fits.

I got these at DigiKey. They are about 1.98mm ceramic LEDs, red. I bought them for marker lights.

You should be able to get them there or I could spare a few no charge and mail them. Email is in my profile.

You can't get them there anymore Chuck.  Lumex no longer makes these and everyone on the planet is out of stock.

Well, I have a few. A friend wanted me to change some classification lights from red to green or whatever, so I stocked up on a couple colors.

Thank you so much for the offer cjack.  I started staring at the shell.  I'd poke at the holes with a hobby knife, stare some more, poke some more not really trying to accomplish anything.

Then, before I knew it, a 3mm bulb fit.  Ooops.  Oh well.  The molded ring in the shell is still present, so it does not look too bad.

Thanks All.

I have been drilling the molded dimples where classification lights should be on my Lionel F3'S and using flat top 3mm LED's with good results.  It makes a world of difference when the classification lights are lit and running around the track, a totally different personality to the mix.

Ron,

Looks like you've sorted out what you wanted to accomplish. Looks good.

As Rich mentioned sponsor Evan Designs, I've found they have an LED product called, Full brightness all around Double LEDs. I've used them several times to replace the bulbs in K-Line caboose marker lamps. I needed something very small to fit into an approximate 2mm hole, yet having a full 360 degree light beam. See that conversion work on this thread;  Grain of wheat bulbs to LEDs.

I converted another K-Line caboose recently to LEDs. Here's the double-LED wire coming out of the un-altered marker lamp hole, meaning I pulled out the bulb and inserted the LED. Done.

A couple shots showing how they worked out.

I use the 2mm post LED's for class/marker lights on diesels.

John,

Do you mean these?  I saw these last night.  Unfortunately my shell posts for screwing to the frame are right in the way of marker/class.  I thought I would have to hack away too much of the post to get these to fit.

Usually at the bottom of the post, it's not a problem to hack a little material away.  If I'm nervous about how much I have to remove, I just reinforce the post higher with JB-Weld at the sides.
