Flasher Volvo 444/445 (1947-56)

Dim or flickering turn signals on an early 544 are often not down to bad bulbs but to oxidised contact surfaces and brittle seals. On the 444/445 from 1947-56 the electrical system runs on 6 volts, which makes the correct bulb and a clean ground especially important – the wrong voltage or a poor spring washer gives a weak or flickering light.
