Tip-up light bar assembly

A tip up integrated light bar assembly comprising:

• frame means mountable to the top of a vehicle for connecting transversely opposite end assemblies;
• a first integrated light bar comprising a first elongated array of warning lights mounted to a first rigid substrate having first and second ends and covered by a plurality of lens elements, said lens elements together at least partially defining a water resistant enclosure surrounding said array of warning lights, said first integrated light bar hingedly mounted to one of said end assemblies adjacent said first end and movable between a horizontal position and a vertical position wherein said second end is displaced over an arc of approximately 90° relative to said horizontal position;
• a second integrated light bar comprising a second elongated array of warning lights mounted to a second rigid substrate having first and second ends and covered by a plurality of lens elements, said lens elements together at least partially defining a water resistant enclosure surrounding said array of warning lights, said second integrated light bar hingedly mounted to the other of said end assemblies adjacent said first end and movable between a horizontal position and a vertical position wherein said second end is displaced over an arc of approximately 90° relative to said horizontal position;
• and
• motor-driven actuator means for displacing said first and second light bars between said horizontal and said vertical positions;
• wherein each of said end assemblies comprises a base that defines a pivot point for the first end of one of said first or second rigid substrates, said base including a bumper spaced apart from said pivot point, said bumper supporting the second end of the other of said first or second rigid substrates when in said horizontal position.
