【Unlimited Emojis to Every Mood】——Explore a huge library of free emojis* in the iGPSPORT app and customize your tail light your way!

 【Knock to Share Emoji】——Quickly knock your taillight twice to instantly share emoji sets with other ET6 taillights!

 【Dynamically Display Taillight Expressions Based on Riding Status】——The expression combination can automatically switch according to different intervals of speed, power, heart rate, cadence, riding distance, and riding time. The iGPSPORT computer must be connected during riding.

 【Temporary parking, Taillights automatically flash】——When temporarily parking, the taillights will automatically enter the double flash state to avoid the lights entering the dormant state after being parked for a long time.
