Fitted 6K hid bulbs to my 54 plate a3 over the weekend, all went well on the install, pretty straight forward. Turned the headlights on and almost immediatly they started flickering even though this convesion kit was meant to be 'HIGH QUALITY'. This sadly was just the tip of the iceburg. The left bulb then started to completely cut out with the bulb warning light buzzing on the dashboard. Switched the ballasts over to see if this was the issue and as i expected the right bulb started to cut out! Pain in the butt, dodgy ballast. Didnt have time to change the bulbs back last night as it got quite wet so drove the car to work this morning not needing my lights. It was a bit drizzly so had the wippers on intermitant. Next thing the waring buzzer sounds 'right headlight bulb out' then my wippers stopped working! Carefully drove it to the garage stopping every hundred meters or so to clear the windscreen hoping it was just a fuse blown... It wasnt! Have now booked it in tomorrow to get the thing fixed!!!! Night mare!!! Never buy HID bulbs off anyone without a good reputation because even though you pay a bit more for them theyre still ****!
