I've added it onto my Adam order. What colours can you switch between?
I know it's not important to have the interior light pack but for me it was a must as I'm sure it will look good when there on, will make the car feel cosy lol.
We have it, you can swtich between; red, blue, green and white.. There may be more. Its a nice to have feature - don't expect it to be boy racer-ish really bright light.. It literally is just a ambient lighting which is quite nice. We always have ours on green as the car is green.
I have the lighting pack and keep it on blue. It looks very cool with the chrome door sills fitted as part of the chrome pack. Gives a subtle blue glow when you open the doors at night as it reflects off the sills. Enjoy!
