Silicon-Power-Diode 5A, (U) 50V, blocking-diode. At accessory rear lights or tail light / turn signal combinations, it can happen that flows from the brake line, a small leakage current when the Rear light cable is connected. This can cause problems. E.g. at LoFs when a trailer is connected. To prevent this, a 5A blocking diode in series is connected to the brake light cable in a way that the current can flow to the tail light but not back. The silver bar on the diode marks the direction to where the electricity can flow.
