Firstly, before I change a Xenon headlight bulb on my 12-reg Insignia Elite (D1S 35watt), is it normal for both dip and main beams to fail at once in the same bulb?
Secondly, I have a simple question about the job. The Haynes manual states that I must first disconnect the battery (ok, no probs), then disconnect the main wiring connector from the headlight unit, then after removing the cover disconnect the wiring connector (presumably from the starter/bulb unit itself?) and turn the bulb assembly anti-clockwise to remove it. Is it necessary to disconnect the main wiring plug as well as the battery? I have tried pulling as hard as I dare on the wiring plug, but it’s not parting. Is there a knack to releasing this plug?
Thanks in advance!
