The IHL-04-A / Brake Eliminator™ is 100% Plug-n-Play and enables customers to have left and right only turn signals, running and brake lights along with license plate illumination and a ground wire. 2011-2017 FXS/B, 2012-2017 FLS/S with OEM RED Rear Run/Brake/Turn Signals send brake light functionality on the same wire that provides turn signal flashing to the rear turn signals. Using our IHL-04-B with our complete rear fender harness, you can now separate the functions and run amber turn signals allowing for traditional style rear lighting. These modules also have a built-in Load Equalizer™ which will allow ANY style of light, LED, halogen or incandescent to operate without any CAN/Bus interference or trouble codes. Perfect for customizing or adding trailers!
