These Philips ultinon pro6000 H4 leds are direct replacement for the H4 bulb

Led elements on these are exactly the same size and place as in the original H4.
Done 5000km with them and no-one is flashing their lights at me.
These are street legal on 2011-16 Beetle in central Europe, close enough to my Porsche 911SC
