Third brake light

The Tune doesn't come with a third brake light, so you have to add your own (for safety and potentially legal reasons depending on which state you live in).

I used a red LED light strip that fits within the t-track, and directly wired it to the stock third brake light (since I was also redirecting the rear view mirror camera at the same time). Here's the LED light I bought: https://www.amazon.com/gp/product/B07MXXDWDM
