The brake bulb model for the classic Dongfeng Nissan Sylphy is T20, while the high-level brake light uses LED bulbs. Brake lights are typically located at the rear of the vehicle and are predominantly red.
To replace the brake light in the classic Sylphy, first open the trunk, then pry open the black plastic cover at the right rear taillight, which is usually secured with plastic clips. After opening the cover, you will see two fixed screws; use a wrench to loosen them.
Next, detach the entire taillight by holding the taillight assembly and pushing it towards the right side of the vehicle, remembering to grip it to prevent it from falling, as the taillight is secured with clips. Once the taillight is removed, you can easily locate the brake light. The brake light is very noticeable when lit and primarily serves to alert vehicles behind to slow down or stop. Improper use or malfunction of the brake light can easily lead to rear-end collisions.
Additionally, it's important to note the replacement of the brake bulb: domestically produced car taillights generally feature a 'one bulb for two uses' design, where the bulb contains two filaments, the weaker one for the parking light and the stronger one for the brake light. Some manufacturers design the bulbs to be insertable with differing pin heights, making them very convenient to use. When replacing, be especially careful not to connect backwards.
