However some brands don't have the cooling fan, just the heatsink at the rear (so better from a functional perspective).
People who have done this conversion had to cut the hole in the centre of the rubber grommet that sits behind the headlight unit, so it's a slightly larger hole. The grommet then seals around the neck of the H4 LED bulb, behind where it fits into the headlight on the metal tabs, with the heatsink behind the rubber grommet in the open air / so getting an air flow for cooling.
The LED lights I bought include the cooling fan but fit into the grommet perfectly, no need to cut anything and I can switch back easily.
I bought them from perfLED...think it's a French company
