Oldsmobile 9433184 Bulb,Rear Seat Roof Illuminate Mirror Lamp

To change a turn signal/parking light bulb, open the hood, turn the bulb holder counterclockwise and press it down, before turning it counterclockwise again to take out the bulb. The side marker bulb can be easy switched out on earlier models by unscrewing it from the back using only a push. Later models need both screws unscrewed before taking the housing off, and you replace the bulb just like on earlier models. The dome/map light needs a careful prying of the lens, pulling down the cover to get it off, and changing the bulb by pulling it straight out; for spotlight-type lamps, start by prying off the lens, removing screws, lowering the housing, and removing the bulb by rotating the holder counterclockwise. To get at and replace instrument panel bulbs, you must take off the instrument cluster, turn the holder, pull it out of the panel, and remove the bulb from the holder. To change the light bulb of the rear side marker on older models, simply detach it from the clip by pushing towards the back. On newer models, take out the two screws, separate the holder, and replace the bulb by pushing it in at the back and turning it counterclockwise. To get to the tail, back up, and parking light bulbs on these models, free their screws, unclip the taillight housing, then rotate the bulb holder to remove it.
