Review on 🚦 DOT Approved 60W 4x6 Inch LED Headlights - Chrome (4 PCS) Rectangular Replacement Compatible with Peterbilt, Kenworth, Freightliner, Ford, Probe, Oldsmobile, Cutlass - H4651, H4652, H4656, H4666, H6545 by Eric Froedge

I just want to start by saying WOW, it makes a difference; and they also have three wires, if you can't figure out how to switch three wires you can leave any modifications to your wiring to a professional, but with that it's basically plug and play, they even include an H4 pigtail for an easy installation. The feeling of light is a bit lighter, the lens looks a bit thin, but it doesn't bother. The housing is a little large for the silver retaining ring on my old headlights, but I fitted it anyway. When it comes to light output they are way better than standard bulbs and I can definitely say they have the best radiation pattern of any LED I have ever bought. The boundary is fairly narrow and straight, with a negligible amount of haze so oncoming drivers aren't blinded. Low beam could be a bit more intense; What I did do was switch the low beams of the inner lights to the outer ones so all four are high and low and that's more than enough for what they were lacking with just two low beams. So far I've only driven around town and the lights have gone out, I'll check how well they handle driving in the country where I live when I get a chance. I took a chance with them and while it paid off I will recommend them to anyone who needs 4x6 headlights.
