Best/cheapest place to purchase a Xenon headlight and get it fitted?

[TIGERPOOL87]

Hi everyone, bit of a newbie here.

Have a z4 coupe and have noticed that the drivers side headlight is intermittent. Sometimes I have to switch the engine off and on for it to come back.

Think the bulb needs replacing (or maybe a loose wire)

I have heard some unpleasant stories about Halfords messing the fitting up, so I was wondering if anyone knew about which bulb I should be purchasing, from where, and any decent garage that could fit it without overcharging.

I'm in west London btw, near heathrow.

Your advice would be appreciated. Thanks all

do you have BMW xenon or aftermarket?

could also be your ballast or igniter.
Have you had any condensate forming in the headlamp enclosure recently?
If yes, then it may well be the ballast and that's a bumper-off job to replace.
had to pump out half a litre of water that had collected on the bottom of my headlamp recently. ballast is therefore toast.
sort of, but not really looking forward to dismantling and replacing.... :|

Currently I have a BMW Xenon, what type of bulb should I be looking for? I believe its an H7, but cant find any which are pure xenon, most are xenon effects like this one
