To make high and low beams light up together, you can add a diode between the high beam and low beam relays. The specific steps are: 1. Open the fuse box, locate and remove the high beam relay and low beam relay; 2. Bend the diode leads into a suitable shape, insert the positive lead into the high beam relay socket and the negative lead into the low beam relay socket; 3. Reinsert the high and low beam relays to complete the operation. Types of automotive lights: 1. Headlights: The front lighting of a car, divided into low beams and high beams; 2.

What does RST mean in a car?

RST in a car refers to the reset button, which can restore the navigation system to its factory settings. In other words, when the navigation system freezes or experiences program errors, pressing this button can reset it, allowing the navigation to function normally. The RST button is usually located on the front panel of the navigation device and appears as a small hole. When the device is powered on, you can use a toothpick to press it and then restart the navigation system. Avoid attempting to reset it unnecessarily. A common scenario for generating a reset is when a connection request arrives and no process is listening on the target port. For UDP, when a datagram reaches a destination port that is not in use, it will generate an ICMP port unreachable message, and TCP will then use a reset.
