Review on 🚛 KASLIGHT 4pcs 4x6 Led Headlights with H4 Socket for Peterbilt, Kenworth, Ford, and Chevrolet: H4651/H4652/H4656/H4666/H6545 by Reginald Ward

products have high quality design. Come with a pigtail to connect the plug. I suggest when you are installing yours and your connector has worn out, just solder and connect the wires directly to the existing wires. I had a loose connection that worked fine, check the wiring, when I screwed the light on the low beam didn't work but the high beam worked. And of course the light came on as I moved the wires. Long story short, I'm not suggesting cutting out the old OEM connector so the OEM light can still be reinstalled if you wish, just splice and plug into the OEM wiring harness and everything is in Order. The lights are bright and do the job perfectly, highly recommended. I am planning to buy another set for my RV. I only suggest that you replace your backlight when it's rusted like mine so you don't risk removing the rusty screws.
