Aprilia Front Turn Signals, AKA Aprilia front indicator lights or blinkers, signal the direction you're turning. Stock front turn signals replace the ones that came on the motorcycle from the factory. Aftermarket ones usually offer some sort of improvement and may be slimmer, brighter, look better, or even re-position the location of the front turn signals. The best options use LED lights, and are plug-and-play. The later means no cutting, splicing, or drilling is required to install them on your Aprilia.
