The second generation brake light of Chang 'an Star broke down in the iron-striking circuit.

The reasons for the failure of the second generation brake light of Changan Star are as follows.

1, completely open circuit, including disconnection, corrosion of terminal, grounding wire not grounded to vehicle body, etc. For this kind of fault, its grounding wire loses its function, which may lead to electrical failure or obvious poor work in serious cases. Under normal circumstances, faults can be found by visual inspection. If no fault can be found by visual inspection, the resistance can be measured.

2. Poor conduction, mainly including broken wire, corroded terminal, loose terminal, poor conduction of base part, etc.
