4 Inch PIAA Driving Lights

Bevinsee P15D H6M LED Headlight Bulb For Kawasaki ATV KLF220 300 KFX400 KVF300
I'm looking at replacing the headlamps on my 2001 KLF 300.  These LEDs are out of my experience range.  Supposedly they are "plug and play". 
What problems am I not aware of? Other controllers, ballast? 
 
Thanks, Cavry.
 

Hello. I am a new member as of today. I had a quick question to ask. I recently was driving mt HONDA RANCHER 2004 GPSscape 400 and my display stopped working. I was driving the atv and all of a sudden the speedometer and the service lights went out. Also the lights stopped working. I am still able to shift gears, change from 2wd to 4wd, and can still select if I want EPS or Auto. I have checked my fuse box and have changed a few of them around. It did not change anything. I was wondering if anyone had any idea of what had happend. Thank you for your time- Trenton 

k I would like to take my one person off road go cart and turn it into a sand rail LIFT it new engine and transmission make it so you have to shift w/ a clutch and all the fun stuff a car has

My mother has a 05 John Deere 650 trail buck ext and someone told me that can am made the atv for JD. I was wondering what model can am it would be so I can find a service manual for it.
