The SoundOff Signal GHOST single and dual lighthead eliminates flashback and "deadened" warning power from tinted windows with our Edge Mount. Edge mounting utilizes a unique u-bracket to mount the small inconspicuous lights to the hood or trunk edge on any type of vehicle. Pivotable light head aims the Extreme Angle output just where you need. GHOST lights are also perfect for Dodge Chargers because they snap right into the grille and are permanently attached with supplied Permanent Mount Screws or Automotive Grade 3M Tape. Lights meet or exceed SAE J595 requirements.
