These new 581 BAU15S PW21W 12V-24V White 42 SMD 6W Can bus LED 2x Bulbs are designed in order to prevent bulb errors when fitting LED to modern cars. This new 581 has a built-in warning controller that stops any errors that you would normally experience with standard LEDs.

That said, unfortunately no car is totally immune to errors even when can bus LEDS are fitted, this is because for safety reasons the can bus LEDs can only have a certain amount of resistance and some cars require more. In cases where normal can bus LED does cause an error, we can supply load resistors to cure this issue, these are available from this link: 50w Resistors for LED bulbs 380 (P21W), 382 (P21/5w)
