It's okay to show support for Trek that way, but something a little more original would be nice.
Back when I still had my white 1973 Mustang, I sat down one day and wondered what I could do with it to tie it in with Star Trek. I never actually did anything, but one of the ideas I had was to completely re-do the tail lights, using the Enterprise insignia as a basis. The arrowhead in red as brake light, star in white as the back-up light, and ring around it in amber as turn signal. With the right materials, you could change any vehicle's tail lights to that setup.
