Yamaha Front Turn Signals are commonly refereed to as Yamaha blinkers or indicator lights. Their purpose is to signal the direction you're turning. Stock, or OEM, front turn signals simply replace the ones equipped on your motorcycle from the factory. Aftermarket ones normally 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. Plug-and-play means no drilling, splicing, or cutting is needed to install them on your Yamaha.
