Review on 12V Universal Motorcycle Electronic Turn Signal Flasher Relay - Adjustable Speed LED Flasher for Fixing Motorcycle Turn Signal Hyper Flash - Black by Ronald Bleimeyer

Fixed my problem with turn signals on Sportster XLH 883 2000. I only had to use 1 for the left turn signal. Previously, the left turn signal did not flash, although it did flash both front and rear. This is definitely necessary if you have modified the turn signals in any way. Don't waste your time with carbide resistors, you're wasting your time and money. I would buy from this seller again.
