4cm: is the minimum distance you must ensure to have between your LED Fan and the Headlight cover cap. If less, your bulb will fail soon due to overheating. The more space has the Fan to breathe, the better will the LED bulb perform in time: adding Rubber Cover Caps even when having 4cm of space is anyways a choice for the good.
Protection: Let's say it, is priceless. When you're working on your Headlight Retrofit, wether it's a LED or HID project, the last thing you want is getting moisture inside your headlight.
