Because of this, since the right dipped light is defective, I tried to change the bulb. Since everything is so installed, I have at least removed the filler nozzle from the water tank of the windscreen wiper system. After removing the rubber, I can now get a little better to the base of the light bulb, but do not know how to release it. There is hardly any space and you don’t see much. Can you tell me how the base is fixed (plugged on or something like that, attached to it) I don’t think it’s screwed)?
