Narrative:

Test flight after earlier gear problem, flew to practice area, extended gear several times manually and electrically, all ok. Returning inbound on ILS runway 33, circle to land runway 24, had '3 green' from GS intercept. Several times on approach, observed and called '3 green' on short final, cleared to land runway 24, hold short runway 33 (landing jet traffic), checked gear lights and saw none! Called and initiated go around. Circled for tower fly-by with gear light now back on. Landed runway 33 safely with equipment (fine) rolling. Gear light bulb found with corrosion and returned to service.
