* Voltage drop: When the turn signal or hazard lights are turned on, they draw a lot of power from the vehicle's electrical system. This can cause a voltage drop, which can cause accessories plugged into the cigarette lighter port to lose power momentarily.
* Circuit overload: The turn signal and hazard lights are on the same circuit as the cigarette lighter port. If the turn signal or hazard lights are drawing too much power, it can overload the circuit and cause the cigarette lighter port to lose power.
* Faulty wiring: If the wiring to the cigarette lighter port is faulty, it can cause the port to lose power intermittently. This could be due to a loose connection, a damaged wire, or a faulty fuse.
If you are experiencing this issue, you should first check the voltage at the cigarette lighter port. If the voltage is below 12 volts, there may be a problem with the vehicle's electrical system. You should also check the fuses for the turn signal and hazard lights. If any of the fuses are blown, they will need to be replaced.
If you are still experiencing this issue after checking the voltage and fuses, you should take your vehicle to a qualified mechanic to have the problem diagnosed and repaired.
