One hypothesis suggests Venus's ashen light is associated with lightning on Venus.
Notes on verification
Multiple independent sources (Explaining Science, Universe Today, ScienceDirect paper) confirm lightning was a historically proposed hypothesis for the ashen light, backed by radio/VLF wave detections from Venera 9/10, Pioneer Venus Orbiter, and Venus Express. Note this hypothesis has since fallen out of favor due to Akatsuki findings, but the claim only asserts it as 'one hypothesis,' which is accurate.
