Re: LED Failures
Reply #6 –
Four years ago, I replaced all interior bulbs with LED (puck driver) lights and have had zero failures.
LED lights without puck drivers will fail due to over voltage when driving.
Many LED failures with puck drivers may indicate a 12 volt circuit spike issue in your coach. LED lights are very sensitive to over voltage. Voltage spikes can be generated by faulty converter, faulty battery charger, faulty alternator, or something else using 12 volt power.
Determining the existence of a voltage spike is not easy. A "fast response" "max voltage hold" digital voltmeter can be used, or an oscilloscope. Note that most digital volt meters are slow acting and will not respond to a voltage spike.
