Those lights only report a failure that must not happen
if the protector is properly sized. Normal failure mode
for any protector means it only degrades. Those lights do
not report that normal failure mode.

For most any location, a 50,000 amp protector will last
at least ten years - in most cases many decades longer. If
your neighborhood has a high number of failures, then a
100,000 amp protector will exponentially increase that
protector life expectancy. And will significantly decrease
its clamping voltages.

Of course, a most critical part is the only part that
actually provides protection. That is the earth ground.
Every protection layer is defined by the only 'system'
component that provides protection. Earth ground. How to
make that 'whole house' protector more effective? Upgrade
the earthing. Every protector is only as effective as its
earth ground. Single point earthing with a connection as
short as possible, no sharp wire bends, ground wire
separated from other non-grounding wires, wire not inside
metallic conduit, etc. All essential to permit a protector
to earth direct lightning strikes without damage  even to
the protector.

Wow; that's quite a mess of unverifiable and misleading
misinformation! Earth ground is NOT the most critical
protection object. It isn't even necessary for protection from
longitudinal surges, in fact. This is a mess of guesses with
an attempt to hopefully sound like you know what you're
talking about, but you don't.

Beware that poster's advice.
