Welcome, Schmutaki.
If you're talking about the corner light, see Shen's tread on making that light blink (stickeyed in the DIY section, I think). It shows how very easy it is to pry the housing out. After that, changing the bulb should be obvious.
If you're talking about the blinker in the headlight housing ... ah, try searching for a "headlight clearing" thread. Might be instrux for removing the housing.
