Strobes N' More E66 MAX Traffic Warning LED Stick - Blue & Amber Emergency Light Bar for Vehicles, Trucks, Police Cars - High Visibility Safety Beacon for Roadside Emergencies, Construction Zones & Nighttime Visibility

This is an incredibly bright arrow bar that has a great selection of patterns. However it would be nice if there was a dim wire for how my install is used. Otherwise two layers of masking tape seem to do alright when I need it dim for events.
