great tri-color led - looks good BUT it will not fit into the 514 signal head facing the front of the head to get the most light output - have had to change my signal plans from three colors to two which is disappointing but for the station exit signals is acceptable - have to go to "0603" size red/green led to fit into the 514 signal head
SHOWCASE REPLIES: The Tri-Color 606 size LED was never intended to fit into the N scale signal head facing front. Clearly, the instructions have it going in sideways. With no compromise to scale, the light output is exceptional and depends on what resisters you use in the line. We find that this LED is the best on the market and works just as it is intended with very bright full light. See a few of the photos for this listing showing an N scale signal head with LED installed as instructed and working as intended.

Nice LED for HO scale signal heads. When I received mine, there was an issue with the instructions that I discussed with the Mfgr. and the instructions were rewritten to make then absolutely clear. With the changes in instructions. the LED works like a charm and has good colors for signals...

Color appropriate and intensely bright.  Should work for your application.

If you're looking for an outstanding tri-color SMD LED or otherwise, check out the Tri-Color LED (606 size), available from Showcase Miniatures, it is fantastic.

This a great LED. With the continuing advancement of technology, these LEDs are a blessing to the model railroading hobby. It is amazing how this small package contains 3 colors.

Unbelievable how small this product is. To be able to mount the wires on the pc board is incredible! And it works! Leds are bright. Only thing I had issues with was dealing with how small the gage of the wires. Seemed impossible to solder to anything, even to themselves. Other than that, a very good product.

The detail, and scale dimensions are excellent, however, the resistor value on the 3 way light is WAY to high. I had to reduce it to 1k for the green light to work. Once reduced the block signal was accurate and worked perfectly. This is in reference to using the two light system.
