In terms of halogen upgrade bulbs (Philips Xtreme-Vision, Osram Nightbreakers, etc): I've been through it all with E85/86 Halogen headlights in terms of modifying them to get the best output without buying Xenon version of the headlights (and some vanity of me wanting them looking better), so I have much experience in this. I've been through it all, I was kind of a guinea pig tester of upgrading these lights if you have the standard halogen H7s: I'm just going to copy and paste my post from another headlight upgrade thread (very informative: viewtopic.php?f=2&t=117875 ). There is a good post on the forum from a member who has fitted all manner of systems and that was his arch engine is your friend. A bit of advice, only fit a 35w system, the 55w run to hot.

If the op wants a link to a really good hid system for just £30 let me know. Regarding self leveling on halogen cars, the adjustment of the headlights is motorised hence hearing the levelling of the headlights when the ignition is turned on, but I'm not sure there is a sensor which constantly levels the headlights, perhaps someone in the know can verify? However when a mot tester switches the ignition they will hear and see the headlights level and assume the self levelling is working. Regarding headlight washers, this is only a requirement on cars manufactured after 2009 and not before, so all e85's are legal with hids and no washers.

That is not correct, testers are advised to check the self leveling system but it is advised not a requirement as systems react quickly and it is difficult to test. Self leveling isn't normally tested at MOT time, washers definitely are.
