Traffic Signal Warning Tape
OPALUS PACK is a manufacturer of traffic signal warning tape for traffic signal cable below marking, signal ducting routes, and road excavation identification. Installed above buried signal cables or conduit runs, it gives excavation crews an early warning before they reach traffic control infrastructure. Orange film, custom printed legends, and detectable tracer-layer options are available for municipal road works, signalized intersections, highway maintenance, and traffic light cable installations.
- Material: Virgin LDPE / LLDPE polyethylene film
- Standard Color: Orange or project-specified color
- Printing: “TRAFFIC SIGNAL CABLE BELOW” or custom text
- Width Options: 100mm, 150mm, or custom width
- Structure: Visual warning tape or detectable tracer wire version
- Use Area: Buried traffic signal cable and ducting routes
Product Overview
Traffic signal cables are often installed below roads, pavements, junction islands, and traffic control cabinets. After trench backfilling, the exact route can be hard to identify during later repairs. This traffic signal warning tape sits above the signal cable or ducting route as a clear buried warning layer.
The printed message tells crews that a traffic signal cable below the tape needs attention before deeper digging continues. It does not replace ducting, conduit, or mechanical cable protection. Its role is route identification inside the trench, especially where road lighting, drainage, and signal infrastructure meet in the same corridor.
OPALUS PACK manufactures traffic signal cable warning tape from virgin LDPE or LLDPE film for flexible buried installation. Standard widths such as 100mm and 150mm are commonly selected for route marking. Other widths, roll lengths, colors, and printed legends can be produced according to project drawings.
Orange is commonly used for signal-related underground identification, while final color selection may depend on local utility marking practices. Custom legends can include ownership marks, route references, project codes, or wording required by road authorities. For future locating, a detectable option can include an integrated metallic tracer layer.
Benefits
- Gives excavation crews a visible warning before they reach buried traffic signal cables or ducting.
- Helps identify signal cable routes during road repairs, junction upgrades, and pavement reconstruction.
- Keeps the page focus separate from communication, fiber optic, water, gas, or sewer warning tape applications.
- Offers visual-only and detectable tracer-layer options for different maintenance requirements.
- Thickness options from 50um to 150um help balance flexibility, handling strength, and buried installation needs.
- Production checks can cover roll width, thickness, print clarity, and tracer layer continuity.
How Does Traffic Signal Warning Tape Improve Road Excavation Identification?
Road crews may work from old drawings, incomplete utility records, or surface markings that do not fully show what is below the pavement. Traffic signal warning tape creates a physical identification point inside the trench profile. When exposed during excavation, the printed warning shows that traffic control infrastructure is close.
For standard routes, the printed film provides visual warning. For busy intersections or highway signal systems, a detectable structure with tracer wire gives another method of route confirmation when used with compatible locating equipment.

Applications
- Traffic signal cable installation at signalized intersections.
- Traffic signal ducting warning tape use above underground conduit routes.

- Highway improvement projects with traffic light cable systems.
- Pavement reconstruction where existing signal cables must remain identifiable.
- Excavation near traffic lights, controller cabinets, and junction crossings.
What Should Be Considered When Installing Warning Tape Above Traffic Signal Ducting?
The tape should follow the same path as the traffic signal ducting or buried cable route, with enough separation to provide warning before excavation reaches the infrastructure. Alignment is important. If the tape moves away from the duct route, it can create confusion during future work.
For detectable tape, the tracer layer should remain continuous along long runs and route changes. Installation teams should also confirm whether the project requires orange film, specific wording, or wider tape for better visibility.
FAQ
What is traffic signal warning tape used for?
It marks buried traffic signal cables or ducting routes before deeper excavation.
Can it be printed with “TRAFFIC SIGNAL CABLE BELOW”?
Yes. It can use this wording or another project-specific warning legend.
When should a detectable version be selected?
Use it when future underground route locating is required, especially for roads, busy junctions, and long ducting routes.
Is this the same as ordinary underground cable marker tape?
No. This product is for traffic signal cable and ducting identification, not general cable, communication, fiber optic, gas, water, or sewer routes.
