Specific Safety Rules
1. Maintain labels and nameplates on the Trailer Lights. These carry important information. If unreadable or
missing, contact Harbor Freight Tools for a replacement.
2. Always wear safety impact eye goggles and heavy work gloves when working on or around lead-acid
batteries. Wear long sleeve shirt, long pants and work shoes. Using personal safety devices reduce the
risk for injury. Safety impact eye goggles and heavy work gloves are available from Harbor Freight Tools.
3. Maintain a safe working environment. Keep the work area well lit. Make sure there is adequate surrounding
workspace. Always keep the work area free of obstructions, grease, oil, trash, and other debris. Do not
use a power tool in areas near flammable chemicals, dusts, and vapors. Do not use this product in a
damp or wet location.
4. Always unplug the Trailer Lights from their electrical connection before performing any inspection,
maintenance, or cleaning procedures.
5. Avoid contact with Battery Acid. If splashed, immediately wash affected area with clean water. Continue
washing area until medical help arrives.
6. Turn vehicle ignition off before making cable connections. Vehicle’s engine must be cooled down before
making cable connections.
7. Connect Trailer Lights cable to proper polarities. Connect black cable to the negative battery terminal,
and the red cable to the positive battery terminal (For a negative grounded system). Failure to do so could
result in sparks, possible fire and severe personal injury.

injury, or damage to the Trailer Lights.
