The lighting holes in the SD45 are for 1.34mm Athearn incandescent bulbs. I can't find LEDs that small.

Rio Grande vs. Santa Fe.....the battle is over but the glory remains!
You can find LED's all over the place. Here's a place I go to alot. Good prices, and fast shipping.

There are many other places, and I'm sure you'll get lots of input.

Look on that auction site for Monster LED's by Big Al Mayo. He uses fiber-optic strands with his LED's to replace the Athearn bulbs.
Disclaimer: I don't have any connection with Al. I haven't even used any of his LED kits. But I've seen some positive reviews, and no negative ones.
Another source for LEDs with fibre optics attached is Ulrich: http://www.ulrichmodels.biz/led-light-with-fiber-optic/ . These are intended for replacement of Athearn bulbs.

If it's the dual lamp light usually used on Rio Grande diesels in both nose and above the windshield, I typically use a short section of .250 Evergreen styrene tube glued behind the openings. I then slip a 3mm LED into the tube. It lights both openings/lamp well and the typical Pyle/rotary beacon simulation on most decoders still generates a good looking effect.
I have used dual SMD LEDs from Ulrich in a few, but this is more expensive, more trouble to install and requires using two outputs on the decoder. YMMV

Alex,
Thanks. This appears to be what I'm looking for.
Wow, cool, another source, and those look great! A simple Athearn replacement. I'm going to have to try them. Looks like they are made to order.

They make led lenz lights for athearn diesels that should fit with little effort, and are pre wired...

He also sells a special drill bit to slightly widen the headlight openings.
