A vehicle includes: adaptive headlights, each configured to produce a continuous beam sweeping effect, processor(s) configured to: (a) detect failure of an adaptive headlight; (b) control the functional adaptive headlight to produce the continuous beam sweeping effect based on (a). The functional adaptive headlight achieves the continuous beam sweeping effect by (1) continuously cycling through a plurality of beam profiles, or (2) continuously rotating the headlights via motor(s).
