Review on Pineeron H11 LED Headlamp Bulb: 9000 RPM Cooling Fan, IP68, 6000K, 4800W, 2 Pack by Jeff Rubio

I found these headlights to work decently. They were easy to install, but fastening proved tricky as the bulb rotates in the ring. It might be better for the manufacturer to have some sort of locking pin that can slide in and out to sync them up so you can line them up optimally in the lamp body. Just insert the ring, squeeze the bulb, press the little knob and turn it and when the beam looks its best release the knob and it will lock it to the ring. Otherwise they worked fine but I would have preferred them to be 3 or 4 way giving the light output of a dead end halogen bulb glowing sine from all sides in halogen. They would be a better fit if they had a different LED board that would provide more coverage. In any case, the color was good and matched the 6000k. I don't know if I would buy them again but if they last longer than your average lamp I would consider it. For them I would probably use them in the bumper light and not the low or high beam.
