Foglights
 

I have a 2013 Mazda 3 that did not come with fog lights and I was wondering if anyone has ever installed these:

2012-2013 Mazda 3 4-Door Sedan / Hatchback OEM Style Replacement Fog Lights - Yellow

If so are they easy to install (apart from removing the bumper), and where does the light switch go??

Thanks in advance
