2001 qx4 interior bulbs application

[QxMan01]

Hey all, I was just wondering, does anyone know off the top of their head what the applications for the interior lamps (front reading lamps, center and rear dome lamp) are? I really want to replace them with the LED's to achieve that Lexus interior light look. Also, if someone can point me towards where I can buy LED's to replace the interior lamps that would be great. Thanks!
