Finally got around to putting these in. I got a dimmer inline from Amazon. I plan to wire into my 12v cigarette lighter line. It looks pretty easy to replace the led strip on the bottom too Incase they go out one day. I got these from car trim. Now that they are tested and working I will toss them in the car. They are a deeper blue in person. My camera sucks on this phone. It is also 10 am on a sunny day.
