Last year I took my car to get the Driver's side head light changed. Now my passenger side head light just stopped working. I looked at the old receipt from the last years work and saw that the HID Bulb part is Xenon 90981-20024 which cost $291. Found it on ebay for $19.99 same exact model. First of all did Lexus Service rip me off? I feel like I should buy the bulb and take it to my mechanic to change it instead of paying Lexus aniother $419 for parts and labor. Any ideas? Thank you
