Chunks

Thanks Kombi and Boondi - yeah the original replacements I got were genuine (about a year ago and German made). However since the lights are playing up again I'm thinking that its the ballast that's a problem. Especially more so since I bought a new pair and the same thing started happening within a week. Anyway I'm going to take the car to an auto electrician and they can remove the bumper to get to the lights and hopefully test the ballasts and globes and determine what needs replacing. If it was easy to get to the ballast myself without removing the bumper I would have tried purchasing a new set online and fitting them myself (and still saved a lot of money by not having to involve Toyota). Thanks Harlo also for the pointer on the ballast type - I was pretty sure they were denso - just needed to know the part number. The buzzing sound is there all the time also when the lights are on. Hopefully all will work out once the auto elec looks at it - especially now with daylight saving coming to an end I'll be driving home from work in the dark soon.

I had bought a set a year ago from the US (an ebay seller) at around $130 each and they were fine for almost a year. Then when this occurred again a couple of months ago I bought another pair from a melbourne ebay seller: http://www.ebay.com.au/itm/A-Pair-35W-D4S-Xenon-Philips-Hid-Bulbs-Globe-Replacement-White-6000K-18M-warrant-/201281936467? This time I went for white colour lights - 6000K. Within a week of installing them the issue started again. I've read on other sites that the ballasts have a lifetime of roughly 7-8 years which is how long i've had my car.

Hello Does anyone know what the brand/part number/specs are for the ballast that drives the HID lights on the 2007 Aurion Presara? I need to get a pair as my lights just keep flickering off after a while and I have already replaced the globes. Thanks

Thanks a lot everyone for the help you saved me a few hundred dollars! I was able to replace the bulbs without taking off the bumper (With kombi17's advice) with two Philips D4S globes I purchased on ebay - from the US. http://www.ebay.com.au/itm/PHILIPS-D4S-X-2-BULBS-42402-C1-42V-35W-P32D-5-OE-FIT-ORIGINAL-XENON-HID-LAMP-DOT-/130577158276?pt=Motors_Car_Truck_Parts_Accessories&hash=item1e67015084&_uhb=1 Turned out they were the exact same brand of globes that were being replaced. Don't understand how Toyota quotes $400+ for each globe when here they were ~ $80 each. Had to remove the battery to get access to the left hand side globe and a bit fiddly trying to remove the bulb retaining clips because the lamp assembly swivels (ie the seeing around corners head light functionality of the Presara). The right hand side was simpler with the only time-consuming piece being removing the screws to the back plate of the light assembly. As for the replaced globes - you could really see the difference - the centre filament part had powdery salts built up in it whereas the new ones were much more clear. Driving, also there is a big difference in the light that is being thrown now - much fuller and brighter.

Hi All I was trying to replace the HID lights on my Aurion Presara without removing the bumper. I got the black cover off and even the igniter cap off the globe but could not work out how to remove the globe itself. Tried to turn it anti-clockwise and clockwise but it just wouldnt move. Is there something else holding it in?
