I owned several cars before (mostly with H4 bulbs) and I can pull out the plugs from the headlights with ease.
On my P5, it seems impossible? I tried pulling hard but it won't unplug from the headlight! Not to mention the wiper washer reservoir is blocking the way.
Is there any special method to pull this out?
