They look very subtle, and I would have to question their effectiveness, LED's are the not the brightest things in the world when there is only a few of them.
They could be boardering on tacky as Mr Mac says, it just depends on how they are installed and the picture doesnt really give a very good indication (excuse the pun lol) of how good they would look.
Tis upto you at the end of the day fella, if ye get em cheap enough though...
