Plug and play installation for stock Harley-Davidson LED Tour-Pak on 2014-2020 Electra Glide Ultra Classic/Lo, Ultra Limited/Lo, Road Glide Ultra, Road Glide Limited and Tri Glide models including CVO applies brake flash/strobe pattern to center Run/Brake portion of the Tour-Pak LEDs and allows left and right corner LEDs to flash/strobe when functioning as Run/Brake/Turn. To provide clear signals, normal turn signal flash will automatically override the brake flash/strobe when simultaneously braking and turning. Riders can easily select from 10 flash/strobe patterns by simply spinning the dial on the Magic Strobes Brake Light Flasher module! It has a sleek design and compact dimensions: 4.2" x 1.4" x 0.6". This unit will strobe the Tour-Pak only and can be used with or without our Magic Strobes BCM or Magic Strobes RSG to apply brake flash/strobe patterns to rear fender brake lights. NOTE: Confirm stock Tour-Pak operation before purchasing. Corners of stock LED Tour-Pak must function as Run/Brake/Turn for brake/flash patterns to affect these sections of the Tour-Pak. BCM may need to be reprogrammed for left, center, and right sections of Tour-Pak LED to flash/strobe when brake is applied. NOTE: When used in conjunction with SMART Triple Play BCM on 2014-2015 Limited CVO, 2015 Road Glide Ultra CVO the center brake only section of the Tour Pak will flash/strobe when the brake is applied. The corner sections will function as run/turn signal only. Although this device has been designed to significantly increase your braking visibility, flash/strobe patterns may not be street legal. *Requires the use of LED bulbs in the rear. Must be used with Low Power Current Draw LEDs such as Custom Dynamics LEDs. The use of Incandescent or High Power LEDs (greater than 300ma) will cause the unit to fail. U.S. Patent 9,566,902 B1
