This might sound stupid, but I like my lights nice 'n blue. My '07 Mazda3 came with factory HID lowbeams. I believe they're around 5000K in color. I have some 8000K HID D2S's but I can't see an easy way to replace them. The Mazda3 manual says I need to take the car to a dealer to replace the HID bulbs but that sounds stupid. How do I just replace the HID bulb?
