Review on 💡 Powerful 2pc 4x6 LED Headlights with H4 Socket for Peterbilt, Kenworth Trucks, Ford Van, and More – Black-Finish, High/Low Sealed Beam (45W) H4652, H4666, H6545, H6054, H4651, H4656 by Antonio Cummings

Seems to be well made so far. Installation was easy. Take a voltmeter and check the harness pins for proper pin alignment. You can drag the pins from the block on the headlights and move them as needed. It's just a small tab that needs to be flipped. I bought adapters but didn't need them because the contacts move easily. The pattern is great and they are very bright. The photo isn't the best but it's low beam. Switch your headlights to low beam before turning them back on as low beam has a T shape so you need to aim them the same way. They fit perfectly on my K5's buckets.
