Deffo possible you can get kits off ebay that replace standard H4 lamps that are used in a lot of halogen headlights. Not sure why you would want to unless you plan to go cruising at night I just bought some LED sidelight bulbs that are HID colour to use in my 2 CV headlights for a laugh!

I saw a westfield on the way to work on Tues with HIDs.

I installed a kit in my daily driver and they have made a huge difference. I just don't use the locost at night anywhere near enough to justify the expense.

Do the H4's have both beams HID or just the dip beam.

Most car HID's fitted as OEM (Not usually H4) seem to just have the dip beam HID and the main beam Halogen.

I read somwhere that the H4 HID's have a single bulb, which is moved by a solenoid to change from dip to main?

Anybody here have any real experience?

For SVA they have to be self leveling.

...and have a washer system too

I have been thinking about these but have yet to hear from anyone who has done it. £50-60 on ebay will get you a conversion kit for the dip beam but as the HID bulb is a very different shape to the conventional halogen bulb do they dazzle?

100 Watt bulbs are locost although not strictly legal . Have had them in my tintop for 10 years with no problems

The only problem with 100W bulbs is that they draw about 17A and my loom is only designed for 10A HIDs only draw about 6A iirc which is micra alternator friendly

The H4 bulbs are driven by a solenoid to change the focal point to give main/dip.

Main problem with these is the shape of the light source is totaly different to a tungten fillament lamp, so the reflector and lens generaly do a very poor job of controlling the light. This gives a lot of scatter and poorly defined dip cut off, blinding other drivers.

I would agree. The "bi-xenons" from china are solenoid based and don't retain the correct position of the filament/arc in relation to the design intent of the optics.

Having said that the low beam only kit I fitted (H7 i think) did have the arc in the same place as the filament when I compared them and the modern ellipsoid design in the headlights is very good at handling beam cutoff.
