For a locost, I’d put together something like this for about $90/pair:

Just 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.

*High quality reflector to shape low beam and glass lens H4 bulb holders from autopal for $32/pair:

*Locost H4 led 35w 4000lm per bulb (hi and lo), slightly brighter than halogens for $12/pair. No fans but low power so it may not be needed and the most power/fuel efficient:

Locost, lowest pwr assemblies with 30w 2800nl low beam for about $25 each but still much brighter and may not be glass lens:

It is also worth noting that while a lot of these assys have DOT markings, that doesn't necessarily mean they are marked as headlights. In some cases they could have the right marks yet not meet the specs for glare.

These were perfect except not much difference switching to high but much brighter and apparently not blinding anybody. You install the adapter ring first, rotate the led body out of it, install the original bulb lock ring, then reinsert the led. Go by the bold specs, not the ones at the bottom which seem to be for a different bulb:
9004/HB1 type, 6000k color, 2000 lumens, 36w (18w each)

Do NOT buy this design led:
https://www.ebay.com/itm/9004-HB1-LED-H ... 2749.l2649

Note the size of the led between the rivets is smaller than most (likely lower output and watts), there is no cooling fan (for lower output cooling requirements), and there is no space for a headlight locking ring to fit between the o ring collar and the finned round body. The collar was poorly shaped with hand tools on the inside and they don't fit. I could modify the lock ring to have a greater id or grind the cooling fins back at the base to make these fit. I'll modify them to fit to see how bright they are.

FYI, typical of headlight leds, the collar goes on, the original head light lock ring behind it, then the bulb goes in and locks with a qtr turn.

Also note crazy high output advertised.

I recommend "C6" design leds. The quality is much better than anything else and the price is about the same.

One thing is the high beam doesn't do much but the low beam makes up for it.
