JTD873GYR 3PCS Model Railroad Train Signals 3-Lights Block Signal HO Scale 12V Green-Yellow-Red Traffic Lights for Train Layout New

These HO Scale three LED signals are a great value! They work well and look good. I'm not sure if they model any specific railroad prototype, but they are realistic enough to not look like toys.

I came across this product listing while looking for other items & for a little over $6 each I thought, why not?They arrived earlier than promised but when I opened the package they looked at first too small for HO Scale. When I took one out of their plastic box I realized it was the same height as what I already had on the layout, but unlike the others (which have oversized targets to accommodate the g.o.w. bulbs available at the time - LEDs did not exist back then) they are wonderfully delicate looking (but made of metal & quite sturdy). They look very good (nicely built & assembled w/nearly invisible wiring)!I was concerned when I looked at the limited instructions, which indicated + and - connections that they might be D.C. only (my accessory circuits are all 10V A.C. - I have 12V lamps that are 50 years old by running under rated voltage) despite the Item Description saying they worked on A.C. or D.C.So I was prepared for disappointment. But to my delight they DO work on either.The required resistor is soldered in-line on the common lead (wires are VERY tiny gauge), although one reviewer's suggestion to add another to the Green lead is probably a good one as the Green does seem much brighter than the other two.So the prospect of installing on an existing layout (replacing old, dimmer, over-sized incandescents) is a challenge but a worthy one. I am very happy with this product!

Great device - form, fit, function. The wires to solder to are TINY. I had to put on my bifocals to just see the wire ends. There could have been a better description of the light functions but when I wired to the diagram Green/Red, No problem. The yellow light seems to be a rogue, or maybe its my wiring, but Green turns to yellow and red turns to yellow+red. It all works, so no complaint.

Hello! I have bought several, but could you help me how to connect them, so that they work, as a signal, since they only remain on and do not flicker, I am assembling my model train.Thank you

I model HO scale and purchased six of these. The signals seem like they may be a little short but they are good enough for my layout. As others have mentioned, the green LED is EXTREMELY bright. I added an additional 2000 Ohm resistor to the green wire to help knock it down. To be honest, the red is fairly bright as well. The manufacturer probably could have put a 2000 or 3000 Ohm resistor on the black wire instead of a 1000 Ohm resistor. On one of my signals, the 1000 Ohm resistor was not securely attached and fell out of the heat shrink tube. I simply soldered it back on. I just ordered six more.

Doesn’t work

These signals are vey nice and work well. They look very realistic.

The product looks cool and is very bright but the wire need to be bigger it makes it hard to solder them to another wire without melting them or breaking them.
