Since I'm taking the dash out to replace the broken vents, install the ipod adapter (ISCH73 by isimple), and to install a MDS indicator. I am kicking around putting 2 x LEDs into each of the vents and wiring it them into the interior lights. That way when the interior lights come on the dash vents should glow in addition to the lighting. I'll be pulling out the normal lights for LEDs throughout the vehicle in the next couple weeks anyway and this seems like an interesting upgrade. What do you guys think? I was also thinking of putting a couple in the box on the passenger side as well.

All lights would be white (~6300k)
