Interior lighting

[Dawn1975]

I was wondering can you install blue interior lighting in a1975 charger

I think you can get blue LED lights at the auto parts store.

Just about any color you want these days as long as you're willing to pay for them.

Not sure how this is a suspension question, but...

I thought the lighting was already blue/green. The cheap way to achieve this is to remove bulbs and paint them with transparent paint. Candy Apple blue would work. Once dry, reinstall.
