closed) switch and bulbs. The resistance of the heating element is low compared to the resistance of the bulbs and the speed of the flash depends on the current. Since 6 volt bulbs draw more current than 12 volt bulbs you will need a
3 or 4 bulb 12 volt flasher to work properly with 2 6 volt bulbs.switch, and are in series with the bulbs. The resistance of the heating element is high compared to the bulbs and depends on voltage. A 12 volt hazard flasher will not work in a 6 volt system.
Are hazard and turn flashers separate items in a conventional, non-electronic system? I still want to place a louder clicker in my mother's Renault Kangoo, but after perusal of the ETAI (that'd be the french version of Haynes, or thereabouts, possibly a bit better quality) manual, it appears that both hazard and turn signals are done by a single flasher. The hazard switch merely connects both left and right sets of 3 lights to the output of the flasher (and it also switches the input of the flasher from keyswitch to always-on, cleverly), while the turn signal does one. The flasher is represented in the schematic as being an electronic block wave generator that drives a relay, and according to the placement schematic fits a standard relay housing (which may or may not be pin-compatible with standard -- it probably is).
