Why led on off switch not working properly? - Computers & Internet

If the lights are not blown, only two things you need to make them work, ground and power. If a wire is broken or not connected properly then they won't work.

It is never a good idea using LED lights with Triac switches, which I assume if what will be in your remote control unit. Good old fashioned relay units are fine but there is often a problem with triac and thyristor controls as they do not expect the type of load that LED lights present and they often do not switch on properly causing all sorts of issues including burning out (invisibly) interal circuitry.

You need not worry, it appears the LED light is a little faulty and your switch mode power supply is OK.
If you are worried then replace this LED.

you are missing something
you describe 3 led lights --2 green and one unlit then you go on about a red led light
suggest that you get in an accredited electrician to check the circuit
it is possible that you are testing with the wring tester

Please check whether the power cable is properly inserted...

The power button of this model fails with time.You need 2 press it tightly and hold it till the LED is on....

try this...


Hope this helped...

Bad Headlight switch...need replacement.

Only "...smack it with a hammer" if you want to buy a new switch! The weak LED's are probably really neon bulbs, as LED's will either work, or not work and aren't as suseptible to voltage changes as neon bulbs are.

The reason for the slightly dimmer bulbs could be because the plastic lens has gotten dirty, or that the bulbs have moved out of their holders inside the switch.

Provided the switch is still functioning properly, you can disconnect the power to the circuit and remove the switch to see if the bulbs have been dislodged from their mounts, or are lose, etc. Otherwise, if working OK, I'd recommend leaving it be.

If your switch does have the LED's on the side, you might find that the mini circuit board has gotten pushed out of its' proper mounting position and by resetting it back on the faceplace to the proper location, could make the lights brighter again.

Hope you find this Very Helpful and best regards!

Did you just replace the bulb with the LED? If so, you probably got the wrong bulb. Make sure it is a 2 circuit bulb like an 1157 dual filament.
