When the car or motorcycle lamp is impacted by the pulse current when it is in the cold state, it is easy to break. Here is to introduce the automobile lighting lamp lifespan prolonging protector which can pre-heat the bulb fuse and make the fuse current rise gradually from zero, so the bulb is prevented from being burned due to the impact current, so the lifespan of the bulb will be prolonged. The working principle of the circuit The automobile lighting lamp bulb lifespan protector consists of the resistor R, capacitor C, transistor V1 and V2, see as figure 7-157.
