The South Bend River Lights in downtown South Bend will have an “eerie effect” Saturday night, Oct. 31, according to Rob Shakespeare, the designer and creator of River Lights.

The River Lights have been programmed so they dim and flicker in honor of Halloween.

River Lights are located near Seitz Park and the Century Center Island.

The display, which premiered in May 2015, transforms the St. Joseph River into a canvas of living art by splashing color from interactive light sculptures on both sides of the river, illuminating the headwaters of the East Race Waterway.

The South Bend River Lights are on from sunset to midnight. After 12 a.m., the lights go into sleep mode.
