All Badlands Intensifiers™ High/Low Modules are designed to provide an inexpensive method to convert a (1) wire incandescent, Halogen or LED light into a dual function or HI/LOW light. Example, if you are installing an old school tail light that has only (1) wire for illumination and (1) wire for ground you would need our Badlands Intensifiers™, IHL-01, Module. This module will allow you to have running and brake light illumination on that (1) single wire! If you purchased a new pair of turn signals and they only have (1) wire for illumination and (1) wire for ground, you would need our IHL-02 Module. You would install this module to the front or rear turn signal output wires and a protected switched 12+ power source. Then the output of our module would feature turn signal and running light functions on (1) wire per side. If room is an issue, (custom bike application) our IHL-03 Intensifier will perform the same functions of our IHL-02 but are only rated for 500-milliamps maximum.
