Almost 3 years ago, forum member jhainer was making infrared sensors and signals with wehonest stuff. Some other folks have used their products. jhainer had no issues so far with the signals, although he's torn down and rebuilt his layout twice. Generally, good products.
Check the voltage feeding the lights. LEDs will last a long time without over voltage. It's kind of standard what voltage colors need. I believe red is 3.3 and green around 2.5 volts dc. I cannot recall if they tied the cathodes (- ) or anodes (+) together on the resistor feed.
I've used both the switch signals and 3 aspect signals from WeHonest. All are still going today. I utilize arduinos to control the signals now, so I'm running them at 5v. They are common anode with a resistor. So the black wire with the resistor goes to positive, and each led wire would go to ground to activate. Before using the arduinos, I simply added one diode to the red wire, two to yellow, and 3 to green. Then connect the red wire to the red block signal rail, and yellow to the yellow block. Green goes directly to ground. And you have a working 3 aspect signal for about $3.
Using the arduino, I can cleanup the ground sensing on the signal rail (software debounce) and have the lights fade in and out, which looks cool. The arduino nano is less than $3, the breakout board is $1.50, and it can control two signals.
If you primer and spray paint the tower mast and ladder with silver metallic paint, you have a pretty decent looking signal for about $3.25 each. I didnt do anything to the switch signals. I thought they were fine the way they were.
