没事的. 如果灯坏了的话, 打转向灯时会闪得特别快.
再担心的话就去车房检查一下电池寿命.
他车能打着就说明没事The battery has certain chemical to hold charges (so when you shut off car and will be able to restart the vehicle). If you slowly drain the battery by leaving lights on while car is not running (interior light, emergency light, external USB charger, headlight...etc), all chemical will become weak and couldn't hold charges anymore and it's time to replace a new one.
