Morphology

pilot + light

This is a straightforward noun–noun compound: 'pilot' (a small constant flame) + 'light' (a lamp/signal) combine to denote a small indicator flame. The meaning is compositionally predictable from the constituents and follows a common English compounding pattern, so a learner who knows both constituent senses will readily infer the MWE meaning.

Etymology

Pilot light is a small flame that stays burning all the time to start a bigger burner. Here pilot means a little helper and light is the flame, so the tiny flame can 'light' the main burner quickly.
