Review on Kairiyard H4 9003 HB2 Led Headlight Bulbs - 55W 9000LM 6000K White - 400% Super 🔦 Brighter H4 LED Headlights Conversion Kit - High/Low Beam Fog Bulb - IP65 Waterproof - 2 Packs by Arunprasath Corso

Replaced existing bulbs in my 2021 Kawasaki 650. What a pain in @$$! There is a tiny wire clip that should hold the back of the lights to the assembly, but as these LEDs have a large heatsink on the back this tiny wire clip is very tight. Once I found the right pliers to press the clip in place, I was spot on. H7 LEDs have a collar that rotates 90 degrees and slopes down. This LED has a big black box halfway to the connection wire (I'm guessing it's some kind of driver or voltage adapter) that puts out a lot of heat. You must have both LEDs in the same orientation or you will have one light higher than the other. Use the garage door or the side of the house to make sure the lights are off on the street.
