Review on Partsam 4x6 Inch LED Headlights: True DOT Approved H6545 H4656 H4651 H4652 H4666 Projector Lens Replacement for Peterbilt Kenworth Oldsmobile Cutlass Trucks - 2pcs Black 60W Rectangular by Duane Hayes

I bought these after some research because another set of lights I bought with an LED grille emitted light like a headlight and created serious glare for oncoming traffic. . Adjusted correctly, these headlights illuminate the road like gas discharge lamps in projector housings. The beam edge is sharp and the beam pattern is wide, illuminating the roadsides very well. The high beam shown in the photo adds another semicircle of light over the low beam pattern. The optics look computer generated, meaning the sample is calculated and the various optical light guides in the devices project the light in the right places to create even illumination. I use them on my plow stand with a heavy duty Fisher 8ft plow. The difference between these and normal halogen lamps is like day and night. Increased safety when driving at night and clearing snow.
