very nice and bright.will add pictures
When both LED H4 lamps are connected in to car headlights , not possible to swith between low/high light. Always only high is lighting! When only one LED H4 lamp is connected in to one car headlight and old standard halogen H4 lamp is connected in to second car headlight then LED H4 lamp is working with possibility to swith between low/high light. Would be fair if seller will return money back for one LED H4 lamp to me.
