I just got a 2004 Mazda 3 and when I got it the right headlight was out. The dealership said they would give me an "IOU" for the headlight and then turned around and said they would just give me money off my bill. I went to get the headlight fixed and they said it takes the High Density bulbs which are $137. I bought the bulb and had it installed and the light still didnt work. The guy said it was the HID Headlight module. I know nothing about cars and the guy cant find what hes looking for. Is the headlight module a part in the headlight or do I have to buy a whole new headlight? If anyone has any suggestions please let me know, anything can help at this point. Ive been without a headlight for 3 months.
