Sounds like a reson8,The LEDs are there as an indication,presence of hold off and tamper health,

If you have no probs with alarm panel and sounder/ strobe test ok then the LED's module has failed,common fault on them.

Possibly, can you see it in the dark?
Most in the day you will have difficulty to see.
If lightening did strike I would expect a fault on the panel too.
Last strike I saw took out the panel, the TV the DVD and all other items plugged in.
You need to get up and look.
Maybe open the panel, isolate mains before opening.
Does it ring in a bell test?
Does the Strobe flash?
