But I installed new LED bulbs today and they still stay on for only 5 seconds :iono:
The LEDs are too efficient.
they do not draw enough power, the CEC determines that is an error,
and kills power to the circuit.
You should get a bulb out and
a message on the MFD at startup identifying the failed circuit.
You must either increase the load by adding a resistor or
use bulbs that draw enough power, typcially called error canceling,
but the added heat of those bulbs will just kill them faster.
Been there, done that.
I finally went to dedicated LED fixtures.
And even the 18 SMD LEDs on just one of those is not enough draw,
it takes two of them working properly to satisfy the CEC.
I like that. with stock bulbs, both have to fail before you get the lamp out.
With the LED fixtures, any failure will be reported immediately.
