Actually, thats a thought - by doing a swap I'll be able to tell if its a bulb issue or the control unit.

Hi Lexus had a look at the car and said that it wasnt a loose connection or anything and that it was the bulb. I suppose it could be the control unit but they didnt mention anything about that.

All, I am sorry if this has been answered many times before but I cant see any references to where is a reliable and reasonably priced place in the UK to buy a HID D4S bulb, either online or somewhere in London/Essex. I have a late 2006 GS300 and the dipped main on the passenger side has gone. Lexus quoted £202 just for the bulb. Thank you in advance.
