Is there instructions on how to install these halo rings in your headlights?

sorry,there is no instruction.It is easy to install these halo rings,you just need to take your headlight apart, then tearing the glue from the back of the rings and paste the ring on it.

How would you be able to change the color of the center LED strip in the headlights from white to match the halos?

Hello, sorry, this package will only contain halo kits. Besides, we don't offer changeable led headlights but only white color. But you could check our dual color changing led lights with RGBW halo, for the center LED, it's remote control; for the rgbw halo, it's Bluetooth APP control. order link: https://www.vividlightbars.com/collections/package-deal/products/package-deal-for-straight-light-bars-pods
