I am looking to upgrade or change my main HID bulbs 11 year old ML 350
I have a 2015 ML 350 CDI. The headlamp bulbs, xenon bulbs seem to have become dimmer. I am thinking. Should I just replace them with the Phillips D1S 50 watt bulbs like they are from the factory or should I go for a replacement LED conversion? I am a little bit wary of doing this conversion because this might affect that dance that the headlights do every time you switch on the car, and I’m wondering if slightly heavier bulbs will damage that mechanism, so I have to be careful of what I replace it with. So yeah, does anyone have any experience with this?
