Parts stores are starting to carry these lights in stock.. moreso, Autozone and Shucks. Napa tends to stick with the stock stuff. They also have an inline resistor for the necessary load to maintain the proper flash speed. Typically if a bulb is burned out your flashers cycle faster due to decreased electrical load and an LED has nearly no load so the system is typically fooled without the resistors. old post, i know, but I couldn't resist. <img src="/forums/images/graemlins/smile.gif" alt="" />
