Look into the headlight reflector before installing the bulb. This will make the job easier.

  • Insert the new bulb into the plastic connector and push the bulb base fully into the connector => see “General Information”.
  • Insert the bulb with the connector into the headlight housing, with the connector lug facing up.
  • First insert the lower part of the bulb => Fig. 260 into the housing at position (A).
  • Make sure the lug (b) is at the top centre so that it engages in the guide as shown in the figure.
  • Look into the main headlight from the front => Fig. 261 and check the installation.
  • Lift the plastic connector in the direction of the arrow => Fig. 260 until the bulb engages in the holder. If this does not work at first, correct the position of the bulb.
  • Check that the seal is correctly positioned on the housing cover.
  • Fit the housing cover into the lower holders and press the upper part into the main headlight until the upper locking tab engages.
  • Check whether the new bulb lights up.
  • Have the headlight aim checked as soon as possible.
