Hella Meist 2 the brightness is explosive as written on paper, but soon my car was getting crazy my fog lights won’t turn on after installing this bulbs, my position lights was also going crazy bright than normally, this LED is explosive but it will go far better than H7 Philips Racing for HIGH BEAM - since my fog lights won’t turn on after this bulbs installed, lastly I figured it out that this bulbs has only 20W without capability CAN BUS system that’s sad because it is just plug n play, luckily I have OBD2 to reset error, put back H7 Philips and my car is getting fine again!You should make 35W-55W bulbs or PUT resistor before installing!DO not purchase if your car have Can bus system and check the wattage your OE to avoid problem or you know how to put resistor in it but you need de-code your ECU ! Now it’s useless and wasted my penny! Thank you
