Flasher front/side Volvo 850 alt 1

An turn signal that stops working or flashes too fast can point to a tired bulb or an oxidized socket insulator – both are common checkpoints when the light has sat for a long time in the heat from the engine bay. On the 850 the front lights and side markers are exposed to road salt and moisture, so contact surfaces and bulb sockets should be inspected when the flash rate deviates.
