Installation Tips

• Select the mounting style (surface or grommet) based on the application and available cutout.
• Use appropriate gaskets or seals to guard against moisture ingress on body penetrations.
• Fuse the positive supply near its source, and use the appropriate wire gauge.
• Run ground to a clean, unpainted chassis point to avoid flicker or interference.
• Program and test patterns before mounting permanently.
• For multi-unit installs, wire the sync lines per ECCO’s specification to keep flash timing aligned.
• Periodically inspect lens, mounting hardware, and wiring for wear or damage.
