We bought my wife's 2008.5 Mazda3 GT with aftermarket HID headlights which totally suck. Now one is flickering and randomly going out when she's driving in the dark. Not good. I want to replace them but not sure what the best options are out there these days, and not sure what we have right now in terms of whether just the bulbs were replaced or the whole housing etc. Looking for recommendations.. whatever will be bright and reliable. Thanks!
