These are CAN-bus error free LED turn signal bulbs on a Volkswagen and come in either xenon white or amber yellow. They serve to replace the stock PWY24W/PW24W incandescent bulbs for a whole new clear look. Not only are they brighter and sharper, they also have a faster response time than stock bulbs. Their clear look also gets rid of the "fried egg" look. Because this LED turn signal bulb is a plug-and-play, there is no modification required.
1.) Remove the tail lamp to gain access to the rear of the turn signal lamp.
