I'm using the switch not the stalk. The installation was straight forward however, for some unknown reasons I'm not able to light them on (both). I have a very good understanding about wiring and fog lights but I don't know what is wrong. The relay is working well I can hear closing the contact and I was able to verify the output voltage and it was OK. I checked the fuse and was OK too. I thought I had bad grounding so I decided to connect the ground terminal directly to the (-) battery, same results.
Finally, I measured the voltage at both connectors and I was having 12.7V which is my battery voltage. It should work but I don't know why is not. I measured ohms across my LED fog lights and measured 700kohms, which it's a little high but I don't know if it is normal for these or came defective??
Am I missing something? Any help would be appreciated.
Taking a guess stab, dont kill me. Wrong polarity?
They are LED lights and LED are very Polarity dependent to work.
Normally red is positive which it's fused and black is negative. It would be a surprise if both LED came wired backward. I think your suggestion is worth it. I'll let you know guys.
how many amp is the rely that you are currently using? that might be the problem? I don't see anything else that would cause such a problem. I didn't have a problem when I installed mine but I did not get mine from Nigel.
I tested the fog lights directly with no hardness, relay or fuse and it worked. So I kept doing troubleshooting and it turned out to be a polarity problem!!! (I will not kill you specONE )
These connectors only can be plugged in one position so I'm not sure if the hardness came wired with the connectors swapped or the connectors in the fog lights.
As you can see in the original wiring the red wire at the fog lights is expecting to receive a positive polarity but it's receiving a negative polarity (hardness blue). To fix that you have three options: 1. Change the internal LED wiring, 2. Swap the wires (blue and red) at the connector of the hardness or 3. Swap the wires (blue and red) at the relay. 1st option is not recommend since you will be working with a factory wiring and it is highly probable that you damage something if you don't know what you are doing. 2nd option seems to be adequate but I did not want to have 4 splices in the connectors plus my hardness was just right there, it did not have enough wiring to work with. I chose the 3rd option for the simple fact that were only 2 wires and I was working stand up .
I do not mind to have the hardness red to ground. This is covered by the jacket of this hardness and electrical tape
I suspect that the problem is the hardness not the fog lights. For regular fog lights (non LED) this hardness would have worked since the polarity is not a problem. Just be aware of this in case you receive this hardness or working with any LED fog lights.
Regarding the fog lights, I'm in love with them. I do recommend them for any IS250/350 F-sport out there.

how long did it take yours to come in. im on week 2 now. im so close to attacking my mailman!!
glad you got the problem figured out. will refer to this thread if mine has the same problem.

Nigel had them in "stock" but it took almost 2 weeks.
Yep, seems like there coming in reverse polarity. Just finished wiring while at work and boom doesn't work. Luckily I remembered this thread. Swapped the wires around and boom foglights!
Thanks again for doing the troubleshooting. I'm so excited there in now!

I'm glad that this helped your installation. Enjoy your foglights!
