Where is the flasher located in the Wuling Hongguang?

In the fuse box inside the engine compartment, some are in the fuse box under the steering wheel, others are in the three-in-one control box, which cannot be removed separately. The control box is located on the left side inside the glove compartment. In high-end models, the flasher is inside the BCM, which can be found under the left A-pillar. Common types of automotive flasher relays include: capacitor-type flashers, vane-type flashers, and electronic flashers. The flasher is designed with a new circuit, consisting of a low-voltage switch circuit, high-voltage switch circuit, pulse generation circuit, two-stage amplification dual-transistor output circuit, and two sets of light indicator circuits. The flasher relay is the central control component that emits light signals when the car is turning or braking. When the car is braking without turning, it controls the circuit to light up the left and right rear lights and trailer lights to signal braking. When the car is both turning and braking, it controls the circuit to make the front, rear, and trailer lights on the turning side flash to indicate turning, while the rear and trailer lights on the other side remain lit without flashing to indicate braking. When the car is turning, it controls the circuit to make the front, rear, and trailer lights on the turning side flash to indicate turning. Capacitor-type flasher: Structure: Consists of a relay and a capacitor. The relay's iron core is wound with series and parallel coils, and the capacitor uses a large-capacity electrolytic capacitor (about 1500uF). Working principle: The charging and discharging delay characteristics of the capacitor cause the electromagnetic forces generated by the two coils of the relay to sometimes add up and sometimes cancel out, making the relay produce periodic switching actions, thus causing the turn signal lights to flash. Vane-type flasher: Structure: Consists of a vane, thermal expansion strip, moving contact, stationary contact, and bracket. The vane is an elastic steel strip, usually tightened into a bow shape by the thermal expansion strip. The thermal expansion strip is made of alloy steel with a high expansion coefficient. Working principle: The vane-type flasher uses the thermal effect of current, with the thermal expansion and contraction of the thermal expansion strip as the driving force, causing the vane to produce sudden movements to connect and disconnect the contacts, making the turn signal lights flash. Electronic flasher: Structure: Consists of a transistor switch circuit, capacitor, and relay. Working principle: The electronic flasher uses the switching characteristics of the transistor and the charging and discharging delay characteristics of the capacitor to control the relay coil's power on and off, connecting and disconnecting the contacts to make the turn signal lights flash. Due to its reliable operation and long service life, electronic flashers are widely used in automotive turn signal systems. Electronic flashers come in various forms, including contact and contactless types, as well as integrated circuit and transistor types.
