is there a light bulb for 2006 torrent

There are bulbs for your odometer light, just ask at any auto parts store, they'll get you the right one. To replace the light in most dash displays you take the trim cover off, and pull the instrument cluster forward, exposing all the bulbs. Hopefully however you don't have one of the nightmare cars that require a great deal more work to get to the instrument cluster like dash removal. I think you're safe however: http://www.fixya.com/cars/t16541085-2006_torrent_odometer_light_burned_out
