Installation of LED turn signals on 2011 to present Softail, 2012-2017 Dyna, 2014 to present Touring, 2014 to present Trike and 2014 to present Sportster requires adaption of the BCM/ECM software, wiring-in resistors or the installation of a Load Equalizer. However, the indicator control light in your dash will still come on with the wrong frequency. The I-Load-IL1 resolves this problem for use with front or rear LED turn signals. Two needed when both front and rear turn signals are upgraded to LED. Not suitable for use with Dual- and Triple function turn signals. Measures 75x22x13mm.
