The pre-wired decoder kit allow you to upgrade WRX's LED turn signal light without the flickering, rapid flashing issues
No modification required when you upgrade to the S4 LED daytime running light bezel and just want to use the LED turn signal (bypass the original turn signal light)
Also good for when you want to replace the 7440 incandescent front turn signal bulbs and convert them to LED
Due to the close resemblance of various connector, ensure compatibility by comparing the shape, checking the locking tab design, and pin counts with the images against your application assembly prior to purchase! Also the load resistor will generate heat, so please mount it on metal or let it hang in the air!
