led flasher resistors
My setup is that the front and repeaters are ordinary lamps but the back are leds. It appears that I need resistors wired in parallel with the leds. Does anyone know if they go as close to the lamp as possble or can you connect them anywhere in the loom as all of the lights are in parallel. Hope it makes sense.
Cheers Peter |

My car is the same using led at the rear, I never really thought about location and fitted them to the inside of the rear tub quite close to the actual lights, I would imagine they will work the same regardless of location
They do get quite hot though so make sure they are in an appropriate position wherever you put them |

Hey, the resistor need needs to be in series with the LED, not parallel! LEDs typically work with a 2-3V voltage, depending on type. The resistor is needed to take the rest of the voltage. http://ledz.com/?p=zz.led.resistor.calculator

The resistor is wired in parallel as it is there to apply the extra load that the relay needs to see to flash correctly, not drop the voltage to the led's.
The other option is to buy a dual load indicator relay. These have a fixed flash rate and will work with either led's, bulbs, or a mixture. Something like the below. This should be suitable for use in the standard Sierra wiring setup. http://www.ebay.co.uk/itm/LED-FLASHE...em5d2f4 c7b2f
