How do you turn ON the dome lights. I noticed last night when i got into my car that I couldnt see shit and i was messing with buttons trying to find the dome light switch. And I couldnt find one. Is it the round knob with the light bulb on it. If so, what do i do to the thing to get emto turn on. I turn the knob every which way and nothing. Could my bulbs be out?..I fear this will classify me as uber newbage. And all i found in the search was blue led domes.
