For a locost, I’d put together something like this for about $90/pair:
https://www.ebay.com/itm/5-75-LED-Dayma ... 935477e312Just a standard 5.75 inch motorcycle bucket with a 40w or less, glass lens versus yellowing plastic, projector led assembly then add the little block of aluminum at the bottom to provide side to side adjustment. Another, more flexible option is to fit replaceable bulb glass lens assemblies for H4 bulbs/leds. Then if you are not satisfied, the watts, lumens, and color can be changed for a lot less $. I could put together a pair of these for about $100 in black. A pair of stud mount buckets costs about $40, in black or chrome.
