Tail Lights Where Can I Find Tail Lights That Look Purple Like On The Older Cars?

Where can I find tail lights that look purple like on the older cars? - tail lights

My BF has a 1986 Chevy Classic Capic. There is a lack of new lights that are purple. We bought a blue apron (blue and purple to red) in the photo, but it does not work. If anyone knows what seems the lights for model cars old "purple line let me know how we can get the same effect with his car.
