As I got older I realized that the bulb was used for disinfecting the clothing by emitting UV light and later realized it wasn't good to look at it either.

Maybe it was an advertising thing way back when. I don't believe dryers have them today. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
