Check the owners manual in your glove compartment. It tells & shows you how to do it. You open the hood and stick a phillips screw driver down into a hole above the signal light. Unscrew the screw nearly all the way. The signal light (lens) should easily slide out. Turn the base of the bulb socket (with cable attached) to remove the light (socket) from the lens. Turn the light bulb to remove it from the socket. The light is a bayonette type of bulb ..... a non-threaded base with two lugs sticking out from the sides. Replace with a standard 21W bulb... I think BMW spec's a Sylvania bulb... but any bulb in this wattage range (and same size) should do. I suggest going with a lower wattage bulb if you deviate from 21W.
I just put clear front corners on my 2000 328 and it couldn't have been easier.Open the hood, insert a screw driver (I think flathead is best) into the oblong hole above the light assembly and depress the locking clip,while at the same time nudging the assembly forward, it should slide out enough so you can pull it out. The locking clip is the flat area you see just below the sort of verticle tab you see immediately below the hole. Unplug the wire, twist the socket, and replace the bulb. To replace the lens simply align the long tabs with the guides and gently push until it seats.
