I love this bizarre Thai TV ad (embedded below) for Sylvania light bulbs.
According to this blog, the light bulbs are advertised as helping to “keep monsters at bay”:
Jeh United Ltd in Bangkok promoted the Sylvania Light Bulb as the way to keep monsters at bay in this off beat TV ad from Thailand. A child at a picnic points out figures from South East Asian mythology. His father fearlessly names them as Kra Sue, the floating head of a female vampire ghost, Kra Hung, a flying ghost, the Banana ghost and others. All is safe in daylight. But when the light goes out…
Via Wise Kwai’s Thai Film Journal, where you can find more info on the ad.
