Problem is message center keeps on flashing main bulb fault, then my horn beeps out of the blue, then my fog lamps switch sometimes on sometimes won't. these all happened afte i changed the main headlight to hid xenon with ballast
Stop retro fitting HID kits to halogen headlights you fool. Don't you know they aren't fit for purpose and you blind everyone else on the road?
The DFT in the UK realised this and ruled the practice illegal unless you change the entire housing unit. You will fail your MOT, but more importantly, you are being a selfish ****.
Just get decent halogen bulbs you numpty!!
First let me just explain something about putting HID bulbs in a reflector headlight, then I'll get to answering your question. High end cars use something called a projector with their HID bulbs and these projectors focus the light into patterns that won't blind other drivers with very perfect cutoffs (no light goes above a certain line). To retrofit a projector into your stock housing it takes a lot of work and careful measurements and thus a lot of time. But this is the only way to do a HID retrofit the right way.
Putting a HID kit into a reflector housing as you did, also makes light scatter everywhere, which creates many hotspots or high concentrations of light that make it much more difficult to see the road. Not only do HID kits in relfector housings make it more difficult to see, they are hugely illegal, and can/may get you pulled over and ticketed by a police officer.
The best thing you could do insted of putting a HID kit in your relfector housing is to get higher wattage bulbs, OSRAM makes some great H4 overwattage bulbs. http://www.rallylights.com/SearchResult.aspx?CategoryID=6
If you purchase from rally lights (you need to purchase them in sets of two( I wouldn't go over 85/80 watt bulbs because it could melt your housing.)
Also make sure your headlights with stock bulbs are aligned correctly, most of the time this alone makes a huge difference as headlights droop over the years.
If you are set on using your HID Kit illegally and blinding all other drivers on the road and willing to live with the risk of getting pulled over by any cop you run into. You will need to figure out how to trick ecu into thinking regular headlights are being used because its detecting the power being drawn for your HID lights to be a fault in the system that needs to be replaced. You can do this by wiring in a 55watt resistor to the circuit.
