Self cancelling turn signal module for use with harness kits with modules above.

Self canceling turn signal module with load equalizer.

#MU15138 SELF CANCELING TURN SIGNAL MODULE WITH LOAD EQUALIZER FOR BIG TWIN AND SPORTSTER

" WIRE PLUS" This 12 volt sold state module provides two specific functions, timed self cancelling and load equalization. By pushing the turn signal button, the self cancelling function will operate the signal for 10 seconds and then turn off automatically. Pushing the button again will cancel the timing process. By pushing the other side's turn signal button, the timing process will be cancelled on one side and started on the other side. The second function of this module is its ability to equalize the load without producing any unnecessary heat. This will allow you to run any wattage combination of turn signal draw from single low draw LED cluster style bulbs up to high draw 60 watt bulbs. This module also allows for the use of front only or rear only turn signals. It does not require the OEM speedometer reed switch and does not support the four way flasher function. Module measures 3" long x 1.5" wide x .75" tall and includes instructions.

Fits all motorcycles with 12 volt turn signals. Will also replace the OEM turn signal module on Big Twin 1989/2000 and Sportster 1991/2003.
