A LED (Light-Emitting Diode) is a two-lead semiconductor light source. LED lamps have a lifespan and electrical efficiency which can last up to 25 times longer than incandescent lamps, and are significantly more efficient than most fluorescent lamps. Similar to incandescent lamps and unlike most fluorescent lamps, LEDs come to full brightness without need for a warm-up time. 

Our products are equipped with a status LED, with this LED you can check if the Squarell Device is operational. The LED can light up green, orange or red. The LED colours/patterns have the following meanings for our devices:

FLEX/SOLID

After installation you can test the CANbus connection by turning the vehicle ignition ON and check the green LED of the device. Now press the brake pedal and check if the green LED of the device blinks black once. If yes, your CANbus connection is OK.
