i had these lights they failed them twice as the inner lights were illegal colour in their words, they adjusted the the lights for me, only to blow an angel eye bulb, improved lighting no not really best off getting ultra blue bulbs from vaux-world had a few probs with these lights replaced them with standard headlights with ultra bulbs far better now adjustment mechanism is crap wind it to far and the screw comes out of the plastic nut and you have to strip the light to gt it back together
