There are several different options for external lights on the Porsche 944 and 951. This article will show you how to replace the bulbs on each of the lights. If you have a bulb that is out, always inspect the electrical connector and the socket before just replacing the bulb. The sockets can get corrosion in them over time which can lead to a bulb not working. Make sure you clean all the sockets with a small wire brush or some Emory paper before installing new bulbs.

Remember when working with bulbs, never touch the glass part of the bulb with your bare hands or anything with oil or grease. The oils from your skin or rags will cause a hot spot on the bulb and result in diminished life expectancy.

Front Side Turn Signal- There is an access panel to the front side turn signal in the forward section of the wheel well liner (red arrow).

Being forward facing it can get cracks in the lens, which can lead to all kinds of dirt and debris in the housing. The previous owner of our project car decided to paint the housing when repainting the bumper. Installation is the reverse of removal.

Front Fog or Combined Lights- The front lower fog or combined lights have a small reflector piece on each end of the unit.

Comments and Suggestions:
Paul Comments: Thanks Nick. Now I can push or pull the center out. Likely from the back. The bumper cover is off.

  Followup from the Pelican Staff: Push it out from the back. - Nick at Pelican Parts  
Paul Comments: Trying to repair RF directional. Orange lens is off. Bulb was burned out and stuck tight, wouldn't press and turn. Right side was flashing fast as in shorted, rear illuminated. Removed bulb with pliers. Trying to remove Assyrian. Removed two outboard machine screws. Ends of assy pull forward, but seems attached in middle. Removed screw and horiz. reflectors. Is it attached in rear, or is something holding it. See drains in picture. How do I remove?

  Followup from the Pelican Staff: The screws for the light housing have to be removed, then the housing. If stuck, you may have to remove the bumper cover to free it. - Nick at Pelican Parts
