If you're looking to go with an LED, you can find pretty decent complete setups on Amazon for around $80-100 or so, and a little less that that for a halogen. Don't forget the fork mounting brackets either; I believe they are 41mm.

If you go LED, there are a number of different options, such as black, chrome, various other colors, integrated signals, halo, etc.

You could also get a halogen lamp, then get a replacement H4 LED bulb. In my experience the LEDs do not illuminate as well at a distance compared to the halogens, but the halogen lamp with an LED bulb from Super Bright LEDs does a pretty fair job. I don't do a ton of night riding so it's not as big a concern.

Edit:

Some various Amazon products for an LED setup:

• https://www.amazon.com/dp/B074PQ8T2B (black or chrome)
• https://www.amazon.com/dp/B073PXW2YC (black bucket with brackets)

A cheaper halogen option with optional LED upgrade:

• https://www.amazon.com/dp/B07QXRK4WN (black halogen bucket with brackets)
• https://www.superbrightleds.com/vehicle/2015-suzuki-sfv650-motorcycle-high-beam-and-low-beam-headlight-bulb?make=75&model=3220&scc_id=1940&year=2015 (H4 LED bulb)

Definitely do some research, there are tons of options out there... and that LED bulb will fit your factory lamp, but I'm not 100% certain it will fit that Amazon lamp. It miiight... but there's a chance it won't. But it might.

Also pay attention to color temperature. The cool white colors above 5K are super obnoxious in my opinion... but that's me.
