- Universal Mounting Brackets (Included): Attach to Foot Brackets via I-bolt, then secure to vehicle via pre-drilled holes and user-supplied screws.
- Vehicle Specific Mounting Brackets: Similar to universal brackets, but designed for specific vehicle models. Attach to Foot Brackets via I-bolt, then secure to vehicle via pre-drilled holes and user-supplied screws.
- Stud Mount: Replaces Foot Bracket. Main mounting bolt goes through the Stud Mount, which then attaches to the light bar using existing screws.
- Headache Rack Mount: Replaces Foot Brackets. Attaches to the light bar using two vertical cutaways. Can be directly mounted or "sandwiched" with a secondary piece using user-supplied nuts and bolts.
Maintenance Features:
- Cleaning: Use water (H2O) with a soft cloth to clean the light bar and lenses.
- Avoid: Car washes (pressure washers, automatic washes, brushes, chemicals) as they can scratch or damage the equipment.
- Inspection: Inspect and test the product daily to ensure proper operation and secure mounting.
- Lens Replacement: Yellowing of clear lenses may occur over time; replacement lenses can be purchased by contacting STL Customer Service.
Important Warnings and Notices:
- Safety: Read the manual thoroughly before operation or installation. Staring directly into LEDs can cause eye damage. Do not cut wires or work on the unit while connected to a power source.
- Installation: Professional installation is required. Do not install or route wires through airbag deployment areas. Ensure proper drilling procedures to avoid damaging vehicle components. Use grommets, cable ties, and looms for wire protection.
- Electrical: Properly size and locate fuses (included by STL, do not use higher amp rating). Connect ground wire directly to the NEGATIVE (-) battery post. Avoid insulation displacement connectors and circuit breaks.
- Interference: Mount light bars a minimum of 12" - 34" from radio antennas. Do not power equipment from the same circuit or share the same grounding circuit with radio communication equipment. Test all vehicle equipment after installation for interference.
- Control Box Placement: Install control box in a location that allows safe operation without losing eye contact with the roadway.
- Wiring: Use SXL type wire in the engine compartment where higher heat resistance is required. Protect wires from hot surfaces and moving parts.
- Warranty: Failure to follow safety precautions, warnings, notices, and instructions may void the warranty and/or cause serious injury.
- Bench Test: Always bench test units prior to installation to ensure all features and parts are functional. Check LED diode/module functionality, flash patterns, non-volatile memory, and for physical damage.
