I have been searching for quite sometime, and yesterday I purchased a 2016 SRX Luxury with 22,000 miles. My only plans at this time, are that I want to add Fog/Driving light assemblies. I am sure I will be asking for advice.

 

Nice...if anyone is looking for a low mileage 2016 SRX in Socal, send me a note! Excellent condition and 1 nonsmoking owner.

 

GM sells a kit for the Driving lights, uses the OEM lights, and switch. I THINK it requires a reprogram of the body control module, which HAS to be done by a dealer, due to having to call in and have the option added for the VIN of hte vehicle in question.
I'm not sure of the cost, but I think you can find it through your local dealer's website, if not the parts department should be able to help you.
