Model Railroading > Led size for headlights in Locomotive

What size LED is use for headlights in Athearn engines Atlas and other manufactures.  Also is there any site's on eBay that one can purchase these LED's. 

Thanks for you help

Mouser.com. it is an electronic parts warehouse. LED. Are much cheaper to get than through retail. Or eBay. Any size you want you can get there. LED are measured in millimeters.

If we're looking for headlight LEDs, that are referred to in the hobby as "Yello-glo" or "Sunny Yellow", how do those terms translate
to Mouser's offerings??  Their Whites might be the blue/whites we saw in the hobby awhile back.  I gotta get back on their
mailing list, have'nt received their catalog since I moved 4 years ago.

kecarden,

 I used Surface Mount Technology LED's soldered with 26-30 gauge magnet wire. The size I used (at least for most diesels) is 0603 (6mm X 3mm or 0.024 in × 0.012 in). If your headlight opening is larger you can use something that fits off the chart I've included. There is a pretty good discussion of Surface Mount Packaging located in the Wikipedia.

Another good source of Surface Mount Technology LED's is Digi-Key Electronics.

best regards,
