If you're looking for a way to add a nice touch of flair to your '13 or '14 Mustang, look no further than this kit. It's a really simple install that took me about an hour and a half (though it could be done quicker by someone who is more familiar with working on Mustang mirrors). The toughest part for me was popping the glass out of the mirror housing, as the retaining tabs love to re-attach... but as long as you have a fairly small flat-head screwdriver and some patience, it isn't a big deal. As for drilling the holes in the bottom of your mirrors, I'd recommend a Unibit; if you don't have one, it'll set you back about $35, but it's worth every penny as it makes drilling the holes pretty effortless. The wire taps in this kit make it a snap for wiring/electrical novices (such as myself) to hook into the factory wiring. As for the final result, the lights really look fantastic. I went with the green kit, and though the white light is supposedly the brightest, the colored lamps are also fairly bright. Starkey really nailed it with this kit. If you're on the fence, just do it... you won't be disappointed!
