For those of us who don't have HID's. I have just purchased Philips Extreme Power +100% low beam globes from Autobarn for $69.00 ($20 off on special). I have used these globes on my last two cars (2010 Commodore and 2006 Kluger). Yhey are worth every cent. Vision in dry and wet is improved. Bright white light and ADR approved - some of the blue ones are not street legal and as the K factor goes up, the penetration and vision goes down. 4000k I find best but up to 6000k probably ok as well. No need to adjust headlight aim. As far as I am concerned, using Autobarn minimises the risk of buying fakes, even if they cost a bit more than R Bay prices.
