When I wanted to add more light to my 450XC-W (Plated and street legal) I did some searching and ended up going to ebay for two of these no-name Quad-Cree XM-L lights for $180 shipped. Advertised at 30W and 3000 lumens each.
The bike already had a headlight switch and fuse which I started by using with an 8” race light. I also wired up the switch that came with the LED lights separately so I can run them on their own or with the 8” light.
Here’s a “before“ pic with the stock light. Yes it really is that useless. Doesn't even show up 10ft from the bike. I manually set the exposure so all the pictures are taken on the same settings. The lights to the right are in my neighbor’s yard about 160ft away. The center of the road at the end of my driveway is 120ft.
Here’s the 8” 60W Halogen light, nice tight pattern. When it’s pointed down low nobody flashes their brights.
Here’s the 8” plus the 2 LED lights. The hot spot of the 8” is barely visible. I've used these for hundreds of miles of night riding an never get flashed by oncoming traffic.
The big trail tech light was heavy and obsolete once I had the LEDs so I made a mount out of some old road sign for the stock headlight housing.
Different LEDs put out light differently and have their own sets of lenses that have different output angles (spot vs flood). These are supposed to be about 25 degrees but they have a lot of spill outside the center hot spot.
There are some drop-in modular versions of similar to these that could be used to make your own light with an existing housing.

Hope this helps motivate some tinkering or sparks some ideas!!
