Location of brake light activation switch

It is possible that removing the LED lights may have caused some electrical issues that are preventing your brake lights from working properly. Here are a few steps you can take to troubleshoot the problem:

1. Check the brake light switch: The brake light switch is typically located near the brake pedal. When you press the brake pedal, the switch is activated and sends a signal to the brake lights to turn on. Check the switch to make sure it is properly connected and functioning correctly.
2. Check the brake light fuse: If the brake light switch is functioning correctly, check the fuse for the brake lights. The fuse panel is typically located under the seat or behind the side cover. Refer to the owner's manual for the exact location and fuse rating.
3. Check the wiring: If the brake light switch and fuse are both functioning correctly, the problem may be with the wiring. Check the wiring for any damage or loose connections. Look for any signs of corrosion, frayed wires, or broken connections.
4. Check the bulb: If the wiring appears to be intact, check the bulb for the brake light. Remove the bulb and inspect it for any signs of damage or wear. Replace the bulb if necessary.

If you are still experiencing issues after checking these steps, it may be best to take your motorcycle to a qualified mechanic for further diagnosis and repair.

Lights are usually on a dual circuit! Left and right have separate fuses, check all fuses or check the fuse diagram on fuse cover or manual to identify correct fuse!

It is either the switch at the pedal assembly or possibly the rear lighting module....without a wiring diagram in front of me...hard to say....but would go with the switch first due to ease of replacement and cost....then have the light module diagnosed if it does not solve the issue.

try to toggle the hazard (emergency lamp switch on top of the steering collumn) on and off rapidly several times.the switch cuts the brake lights out for the 4ways to flash. if the 3rd brake-light still works the fuse is good.if the 4ways work and you cant get the brake lights to work then the multifunction lever has to be replaced which has the hazard switch on it. this is a vary common problem but the steering wheel has to be removed along with some other components behind the wheel which require special tools and knowledge. usually you can get the brake-lights working again by working the button for the 4ways rapidly until the brake lights start working again. good luck.

Sounds like a brake lamp switch or fuse. Check all fuses electrically, with a test probe you can purchase from any auto parts store. Go through each fuse with the probe touching the end or tip of the fuse after clipping the lead on the probe to a good ground. If the probe lights up at both ends of the fuse, the fuse is sound, if it only lights up at one end then replace that fuse and if the probe does not light up at all, that fuse is not active so turn on the ignition but dont start the motor. The brake lamp switch is attached to the brake pedal. It may have a single wire or several. All the switch does is connect the brake lamp circuit to an active supply rail so, The switch should have one active wire and the other wire should become active when the pedal is pressed. If it does not, replace the switch. If it does, then you may have two blown bulbs in the rear lamps or a damaged wiring harness to the rear lamps and you should seek the advice of a qualified person. Start with the fuses, then the switch, then the bulbs..and remember, you may have more then one fuse panel in the vehicle so check under the hood too..

Bulbs are bad, most bulbs burn out around the same time withing a day or two and both of your brake lights may have gone bad. Try with the simple and inspect the bulb and replace if you see any discoloration to the glass on the bulb. Good luck and than you for using Fixya.

If the high level brake lamp works and the other 2 lamps have good bulbs, then there is a power loss, most propably with the installation. You should go to an auto electrician to see where the break is.
If someone has recently done any work on the electrics, you should recheck. It is not a seperate fusable power supply system or brake switch for the high level brake lamp, it will take its power from the fused system that the other 2 have.
Hope this helps

Hi my name is mike ! make sure with a test light that you have 0 power to the light back ther ,and if not then take a test light and check down by the brake pedal at the wires that go to the brake light switch ,check all of the wires for power and there may be more than one that has power to it ,do this without hitting the brake ,remember which wire or wires had power to them ,then hold the brake and one of the wires that didnt have power before holding the brake ,should have power to it now because when you hold the brake on it should close the brake light switch and send power to the lights ,if you dont have power coming through that switch when holding the brake pedal down ,then replace the switch .

It sounds like a wiring fault - an earthing problem. Have a look around the lights/inside the lights themselves.. rear and front lights, brake lights, etc ...check the wires for corrosion/splitting. In particular check any black earth leads where they attach to an earthing point.
