[0041] The power supply of the circuit system can be set separately, or when installing the turn signal of the present invention on the vehicle, it is electrically connected to the vehicle-mounted battery. It should be noted that the focus of the present utility model is to organically combine the projection function with the turn signal to enrich the lighting atmosphere effect that can be created and attract the attention of others to improve driving safety.

The shapes of the partition frame 16 and the preset groove are both "Y" shaped, so that the taillight area 12, the left turn signal area 11, and the right turn signal area 11 form a "pin" shaped distribution. When braking, the taillight area 12 lights up, or it can also be set that the taillight area 12 and the left and right turn signal areas 11 together serve as brake lights, and the independent taillight area 12 lighting up represents other meanings, such as parking.
