OSRAM Cool Blue Boost H4 (Twin)

5 Good bulbs

Very Close to white without going blue

5 Good Quality

5 Styling bulbs at 5000K

This is some great styling bulbs, the performance should be better than standard bulbs, but these are 100/90W so it should be better if there is some quality behind these bulbs. I like the white light in the headlights and on the road.
