I put this in my 21 KLX300sm and it works perfect. I do recommend it. Basically any bulb with the H4 connector should just be plug and play. Buddies say my headlight is way brighter now and looks nicer too.

I got this LED bulb on Amazon. Works well.
I got a brand new DRZ a few months ago and wanted to keep the stock shroud as well. Here's the link to Amazon it's a $20 bulb that's very bright I am very satisfied! You will need to use a little bit of WD-40 around the rubber boot and the bulb to squeeze it on there because it's a little larger than the stock bulb but it will fit!

I have done this mod after finding the sharp light line of the Daymaker to be distracting. The bike vibrates and it caused the Daymaker to also vibrate and I hated seeing the sharp line of the light shake while on night rides even though I loved how bright it was.
The bulb I ended up going with is this one: AUXITO H4 LED Headlight Bulb... https://www.amazon.com/dp/B092SHMWQZ
Getting the rubber boot around the bulb was a little tricky as the bulb is slightly bigger than the stock halogen. I used a butter knife to pry up the rubber boot and get it around.
The bulb itself is very bright and works great, you can even see it illuminating street signs during daytime. The bulb doesn’t have a fan so no need to worry about that going out, it doesn’t heat up really at all compared to a halogen, it’s bright and the light temp is super visible, and it was reasonably priced. The beam pattern seems identical to the halogen bulb in the stock housing. I cannot speak to compatibility with a smaller housing/reflector though.
