The Lights Out (MMS-ADV-50) multi-message sign is a 600 × 600 millimetre traffic yellow panel designed to warn motorists that traffic signals ahead are not operating. Commonly used during power outages, roadworks, or signal maintenance, this sign provides advance notice for drivers to approach intersections with caution, give way as required, and proceed safely through uncontrolled junctions.
Manufactured in compliance with Western Australia Government traffic control requirements, the panel is fully compatible with the approved modular multi-message frame system. It can be displayed independently or paired with related warnings such as “Traffic Lights” or “Prepare to Stop” to form a compliant, adaptable display. The approved frame supports flexible layouts—two 600 × 600 millimetre panels above a 1200 × 300 millimetre panel, or one 1200 × 600 millimetre panel above with the same 1200 × 300 millimetre panel beneath. This modular design allows councils, contractors, and traffic managers to update signage quickly and cost-effectively as conditions change.
Constructed with CL400 Class 1W reflective material in traffic yellow, the Lights Out panel ensures excellent visibility in daylight, at night, and in adverse weather conditions. Its weather-resistant, durable build complies with Australian traffic sign standards, ensuring long-term reliability in demanding outdoor environments.
By alerting drivers to non-operational traffic signals, the Lights Out (MMS-ADV-50) sign improves awareness, reduces intersection risks, and supports safe road management during outages or works.
