Why is the left turn signal blinking fast?

[ColtonRose]

If the blinking speed is fast, it indicates that the bulb is burned out, causing the turn signal to flash too quickly during operation. Below is additional information: Blinking function: The blinking function of the turn signal is achieved through a strobe oscillation circuit, with the core component being the flasher unit. It controls the periodic on-off of the current to achieve the flashing effect. Types of flashers: Common flasher types include capacitor-type, reed-type, and transistor-type. These three types have different characteristics and varying fault monitoring capabilities. Turn signal circuit abnormalities: When one or more turn signal bulbs on one side are burned out or have poor contact, the capacitor-type flasher will cause that side's turn signal to remain lit without blinking, indicating a circuit abnormality. Reed-type and transistor-type flashers have simpler structures, smaller sizes, more stable blinking frequencies, wider applicability, and more noticeable monitoring functions.
