My HID would periodically stop working. The problem was a wiring connector but I never found which one as taking it apart and reconnecting was enough to get it working again.
When the dipped beam burner failed I went to LED bulbs with H7 fitment. They produce more light on paper, but as there is more at the blue end, so effective brightness is much the same as HID.
I used bulbs with a passive heat sink that sticks out the back making it difficult to seal the lamp case. Later models with a fan cooled heat sink would be better as a boot could be cut to fit between the circular fan casing and the lamp rear cover. You will need to make a patch lead to connect the wiring loom to the HID bulbs. The original H7 connectors are inside the lamp casing so can't be used.
I can't find the actual current draw of the LED bulbs. When they quote 120 watts they mean equivalent light to a halogen. Some say 55 watts but as LEDs are supposed to use a lot less energy this sounds odd.
However, the light output of mine is about the same as the HIDs so more than enough and they might use less power. The emitter does not get hot so the lamp reflector is not getting cooked. Any waste heat from the LEDs is taken away by the fan cooled heatsink on the back. The emitters on mine are only slightly larger than the halogen filament coil so beam focus is good.
