Parking Assistance System with LED Display, 8 Black Sensors - Front and Rear

The parking assistant is an advanced system that monitors the space behind and/or in front of the vehicle.. Uses ultrasonic waves to detect whether the vehicle's path is clear of obstacles when parking. If it detects any obstacles, it informs the driver with an audible and/or visual signal, recommending that they exercise extra caution.. The parking assistant kit consists of ultrasonic parking sensors, a control unit, a loudspeaker and/or a display, a hole saw and the necessary cables. Usage: For detailed instructions on how to mount the sensors, please refer to the instructions in the box. Connection instructions: Black wire - ground Yellow wire - power supply (+) DC 12V from reversing lights (to activate the rear sensors)Red wire - power supply (+) DC 12V after ignition White wire - variants:∫ (+) DC 12V for STOP light or brake pedal sensor: the front sensors will turn on for 10 seconds after pressing the brake∫ (+) DC 12V for additional button (e.g.. on the dashboard): the front sensors will be turned on/off with this button∫ (+) DC 12V to existing vehicle installation point (e.g.. front halogens): the front sensors will start when the halogens are turned on. The front sensors will operate for 10 seconds after the voltage pulse is applied (+) DC 12V on the white wire, or continuously if the wire is under constant voltage (+) DC12V. Engaging reverse gear (when reversing) the system will automatically switch to the rear sensors, even if there is voltage on the white wire that activates the front sensors (+)DC12V. After switching off the signal from the rear sensors, the control unit will automatically switch to reading the front sensors for 10 seconds.. The system always transmits the readings of either the front or rear sensors, not both at once. Important!  Keep out of reach of children. Technical Specifications: 1. rated voltage: 12V2.
