Wireless installation makes these turn signal mirrors the easiest to install on the market! Add the safety benefits of wide-angle mirrors for you, the driver, and turn signal lights for drivers who might be in your blind spot. When you turn on the factory turn signals, the Turn Smart LEDs are activated and blink in conjunction with the factory signal lights. Attached to your mirrors with 3M double-sided tape, the lights charge themselves by solar power. It really can't get easier to install this important safety system.
