Wiring custom LED's into fog light adapter/plug

[JayW]

Vehicle details:

Polo 6R R-Line 2013 1.2 TSI

I've recently got some LED's off the bay to wire into my WRC side grills, i've wired them up using spade connectors and splicing all positive's together and all earths together as per pictures. However when i connect them to the foglight plug on my car, they are very dim and flicker badly. They stay on even if the foglight switch is turned off and flicker even more if i turn the fog switch to on.

I believe i need a resistor to stop this and to bring the lights to full power, is this correct? Anyone know how to work out what size resistors i need?

The bulb specs are as follows:

https://www.ebay.co.uk/itm/10PC-12V-9W- ... 2749.l2649

* Voltage: DC12V
* Output Power: 10W
* Real power consumption: 2W/pcs
* Operating Temperature: -40oC~105oC
* Light source: LED
* LED Color: White 6000K
* LED Type: High Power 5730 Chips
* Luminance: 110-120LM













Any help is much appreciated.

Have you tried putting 12v on to the lights just to check everything is fine.

But it could be to do with the lamp monitoring checking the lamps as to why it is pulsing.

Hi,

Yes i did and they work fine at full power too, no flickering or dimming.

Could this be a canbus error thing then? Will wiring in a resistor resolve this?

Also does anyone have a pin layout for this headlight plug?

Yeah it's probably the lamp out checking that is making it flicker.

You could wire a resistor across the + and - but it would need to be a fairly low value and quite a high power one.(I'd try something like 100R 10W )
