Unless you have your car on the track a lot, probably not worth it unless you like that kind of bling.

My other car came with a shiftlight. It was smart enough to analyze how you were driving and pick shift point based on how hard you were driving. The light would come on early to save fuel if you were driving really lightly, and if you were driving hard, it wouldn't come on until you were almost at the rev limiter. Nice piece actually. After awhile, especially at night, it just became an annoyance, especially when the bulbs (it's an old car now) started burning out rather frequently. I just stopped replacing the bulbs after awhile so it doesn't come on anymore. I don't miss it.
