If you are dissatisfied with the quality and brightness of the headlamps on your Yamaha 650, you can update your account with the high-intensity aftermarket (LED). LED headlights emit more light, last longer and consume less energy than the halogen headlights that come with the Yamaha 650. Although the LED headlights require some additional wiring to the installation, the process is simple and straightforward.
Turn off your Yamaha 650 if it is on.
Disconnect the h3 led light bulb harness from the headlight socket on the back of the round lantern assembly.
Remove the two screws on the headlamp body to remove the headlight lens.
Put on latex gloves to prevent oils in your fingers from damaging the headlight bulb. Remove the h3 headlight bulb.
Insert the white h3 headlight bulb from the replacement aftermarket into the headlight hub. Replace the headlight lens and secure it in place with two screws.
Mount the thin ballast that comes with the LED installation kit on the back of the headlamp bucket with the double-sided adhesive pad included in the kit. Connect the headlamp wiring harness that you previously removed in the ballast. Connect the built-in harness in the ballast wiring to the headlight socket.
