Have you ever seen LED replacement for oridinary car lightbulbs which were advertised as CAN compatible? Modern cars can measure every lightbulb current consumption and inform driver about broken lightbulb when current consumption is to low. LED replacement uses less current which often causes car to "think" that lightbulb is broken. So somebody came up with an idea - CAN compatible LED is normal LED with paralel resistor just to increase current consumption. Does it make any sense? No, you have LED lights which consume approximately the same amount of energy:/
