Flashing Speed

[deezee]

Right, I've got all my lights connected up now on the loom. Everything works and apart from some tidying, its going great. However the flashing speed of the indicators is too fast.

The indicators are all bulbs (no LEDS) with the following ratings, 10W front, 5W Side, 12W rear and whatever the bulb in the dash is. Is it simply a case of not enough load on the flasher relay? When the hazards are put on, they flash at the correct speed.

I'm aware that some production cars have / had electronic flasher units and aren't prone to loading issues. Does anyone know what cars these come off? before I head down to a scrappy.
