Modification of general motorcycle lamp

The inspection method for the failure of the motorcycle turn signal: check whether there is power supply in the fuel gauge, power indicator, horn, etc. If there is no power supply, it may be the failure of the ignition switch, battery, and power supply; If there is a power supply, the four turn signals do not light up, which may be caused by the damage of the flasher. You can directly check the flasher, whether there is power supply for the input of the flasher. If the flasher ignition switch is still not on, check the turn signal switch and turn signal; If one side of the steering lamp does not light, or only one light is on, but the brightness is insufficient and does not flash, it may be that the steering switch cannot turn on the flasher, and the flasher can only work when the front and rear lights are on together; The four turn signals and the turn indicator on the instrument do not work. Generally, the flasher or the turn switch is damaged. First, replace a motorcycle vehicle accessories or short-circuit the flasher wire. If the turn signal is on, it indicates that it is a problem with the flasher. Replace it with a new motorcycle vehicle accessories. If not, check the turn switch again.
