## Description

581 (PY21W) 27* Amber SMD LED Canbus Indicator Bulbs (2 x LED) No More OBC Errors! These are the Brightest 5050SMD LEDs Innovative Design - Prevents Bulb Warning Errors Easy Intallation - Simple Plug in & Play! Price is for 1 pair (2 x 581 LEDS) Ingeniously developed, these new 581 LEDs 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 canbus LEDS are fitted, this is because for safety reasons the canbus LEDs can only have a certain amount of resistance and some cars require more. In cases where normal canbus LED does cause an error we can supply load resistors to cure this issue,these are available here. Model: 581 PY21W (OFFSET PIN) Colour: Amber (27 SMD chips) Power: 12v (27 X 5050 SMD)
