The Fang turn signal light inserts fit straight into OEM bullet style turn signals and are a great way to add modern styling and class to your bike while also increasing visibility. Ciro has engineered the lenses to amplify light output for maximum brightness. A Load Equalizer is required for 2002-2013 Sportster, 2000-2010 Softail, 2009-2011 Dyna and 2010-2013 Touring. All lights are sold in sets of 2 for left and right and are DOT approved.
