Advanced 2-phase synchronization technology adds another powerful dimension to the most effective, compact, lightweight warning light available.

Solaris™ reflector technology delivers bold blocks of light and superior off-axis reflection. Molded scalloped facets at the rear of the reflector direct LED light forward to form an impressive block of illumination while two inboard side reflectors mirror high intensity LED light to the side, producing wide-angle off-axis warning. Available in single or dual head configurations.

This specific Viper S2 is a synchronized unit which uses an advanced 2-phase wire technology to coordinate flash patterns among up to eight lights at once. Synchronized light patterns can be set to work as either concurrent flash or opposite flash.

Each unit comes with a snap-on flash guard, reflective tape, bracket, and hardware (swivel type bail bracket and suction cups) to allow mounting almost anywhere inside the vehicle.

  • Available single unit colors: Amber, Blue, or Red
  • Available dual unit colors: Amber/Amber, Blue/Blue, Blue/Red, Blue/White, Red/Red, or Red/White

      As far as the eye can see. That's not a very good answer for your question, but were not sure where you are going with this. If you are parked on the road and there's nothing between you and the car I would think it could be seen.Sorry best we can come up with.

  • Q:

    Hello Again. I just posted some questions regarding the differences in the Mini-Phantom lights.
    Looking at this LED Viper light, does this one 'Blast" the Mini-Phantom off the charts. I know this costs more for the Two Head version but if there is a major difference in Visibility I would need to lean that way with my purchase. The old time Revolving Lights seem to have alot of Visibility on their own. Perhaps one on each side of front dash would be fine for Budget and Visibility purposes.
    I would really appreciate any information or advice from more experienced people would be greatly appreciated.
    Thank You
