I put dual relays in for my headlights, one for the low and one for the high beam and it made a great difference, but then I went with DOT approved LED headlights and it is like night and day. There are two kinds each about $150 each. One is from Grote
, and the other, which I have is Truck-Lite 27270C 7”
round LED H4 headlights.
You can Google each one and find them on eBay, Amazon and most times they will be under the $150 each price range. The Truck-Lite ones come with a 3 year warranty, and since they are DOT approved won't blind anyone like the conversions where the housing isn't setup correctly.
