Drop in LED headlight or PIAAXtreme white ?

My high beam on my 08 burned out .I checked out the net for a LED replacement bulb .But they all look too big for the housing to fit the bulb . So i`m thinking just dropping in a PIAA bulb instead .

Anyone have luck with the DX and LED bulbs ?

Looking for simple plug and play .
