Since I bought my Mercedes ML W163 (2003) in 2020 which has xenon light bulbs I changed them around 3 times on both sides. Putting in a new ballast and bulb is expensive and frustrating because the halogen bulbs on my other car last 3 times longer. I don't know if thats normal, but if not what could be the cause of it. Thanks
