Flashing Speed
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. |

you are exactly right,
basicly you just need more load on the circuit, i have the same problem myself after changing my front indicators for IVA fit a resistor in serise with a pair of your lamps front pair, side repeator pair or rear pair to increase the load 1 ohm on ither side should do it if not you can pit the resistors in seriese with each other and simpaly add the values together 1ohm + 1 ohm + 2 ohm simples tilly |

Normally 21watt bulbs are fitted front and rear and 5 watt side repeater this should give you the increased load.
60/120 is the flash rate per min for MOT/IVA.(I think) |

Just been back out to garage and the rear bulbs are 21W units (the 12 was the voltage DURRR) I have a load of these resistors that I had for replacing, out of production, bulbs with LEDS on my tintop. Can anyone tell me what ohms they are? I'm not lazy, I'm colour blind. The packet simply says 12V resistors.

Put 21 watts in the front and see what happens you should not need to put resistors in the system and they will add a small amount of heat to it and they look about 3 ohms by the colour but its not a good picture.
The hazard relay is meant to take 4x21watts plus 2x5 watts for the side repeaters. |

I've gone back to the car, popped in some 21W bulbs on the front and it works fine Sadly the 21W bulb is far to big to fit inside the front indicator housing. Looking on the internet I can't seem to find a small 21W bulb. So its either resistors or a different flasher / hazard relay.

At least you have sussed out why and learned a little in the process.
Possibly try out some large LED's and resistors but I think you will need something to increase the load as before. Audi/VW fit 12v 6 watt halogen bulbs to sidelight and they are very bright. Good luck. |

If your bulbs are not the correct wattage they may not be bright enough to pass the IVA.
