The Flasher Relay is defective. Replace it. Flasher Relay is located in the front seating area, driver side, under dash, mounted above kick panel. It pulls out.
4 way flasher switch on top of the steering colum is what I have found better known as the turn signal, wiper, cruise control.
Check the fuses and the bulbs.
Most likely a fuse or a bad ground.
I would almost bet it's the directional light switch in the steering column. Do they not work when you step on the brake pedal also? I'd put my money on a faulty ground at one of the turn signal lights. Watch the bulb when you turn on the turn signal with the headlights OFF. If both filaments are glowing in any bulb, it doesn't have a ground.
in dash lights
Fuse, wiring, bulbs
Start by checking your fuses. Then bulbs. Then switches in that order.
To check your headlights, taillights, brake lights, and turn signals using their reflection, park your vehicle about a few feet away from a flat wall or garage door. Turn on your headlights and observe the reflected light to ensure they are functioning. Activate the turn signals and brake lights one at a time, watching for their reflection to confirm they are working properly. This method provides a clear view of all lights without needing another person to assist.
There is essentially no restriction on using brake lights and turn signals at the same time, as they both signal actions/intentions that are often used in conjunction with one another. The brake light signals that you are using your brakes and slowing down, and the turn signal shows your intention to turn. As you will usually slow down as you come up to a turn, there will be many situations where both signals will be on at the same time.
well if its a super pocket bike headlights turn signals brake light horn
blowen fuse or lights check fuse first
Your question was a little unclear, does the brakelight work when the headlights are off but not when they're on? If that's the case, it's a ground problem. Check the ground to the tail light/brake light assembly. If the brake lights don't work at all, check the turn signal switch. Brake lights are routed throug the turn signal so that you can use the same bulb for turn signal and brake light. BTW, if you have an air bag, don't attempt to replace or inspect the turn signal switch yourself. It can be very dangerous.
