Purchasing Guidelines

• Only persons authorized by the district and/or who are familiar with the guidelines and best practices should purchase fleet lighting.
• All lighting will meet SAEJ595 or SAE J845 Class 1 standard, verified by an AMECA (Automotive Manufacturers Equipment Compliance Agency) certified lab.
• For higher intensity lighting such as longer light bars, bright white LEDs, etc. the use of a dimmer function should be considered for use during night time operations.
• Vehicles requiring fleet lighting will be upgraded on existing vehicles to comply with these guidelines depending on remaining life of the vehicle.
• For new vehicles, the purchaser of the lighting equipment should contact the supervisor for the location where the vehicle will be assigned to verify the intended use and classification of lighting.
• When making a purchase, do so from a reputable vendor and require certification of the testing requirements. Also, discuss with the vendor the desired application to ensure the product is correctly utilized.
• The manufacturer must approve supplemental lighting to any mobile attenuator.

Installation Guidelines

• Only persons authorized by the district and/or who are familiar with the guidelines and best practices should install fleet lighting.
• Installation should be as “clean” as possible with no hanging or unsecured lighting inside or outside of the vehicle.
• The switch for the fleet lighting shall be easily accessible and visible to the operator. If possible, the switch should have an indication light to prevent the light being inadvertently left on.
• The light should not be installed in such a fashion that could cause a reflective glare inside of the equipment/vehicle that could cause interference with its operation.
• All lighting equipment should be permanently attached to the vehicle; temporary mounts, such as magnetic and suction type devices, may only be used in limited situations with approval from a General Services Manager.
• Beacons or light bars should be installed at the highest point possible and should not be blocked by any equipment such as v-beds, luggage racks, etc.
