300mm LED traffic lights: choose the signal and countdown arrangement
The 12-inch catalogue includes different indications and assemblies. Specify whether you need a vehicle signal head, an arrow signal, a pedestrian display or a separate traffic light countdown timer; these are not interchangeable order descriptions.
- Square red/yellow/green countdown timer: a separate display for remaining signal time; review the selected timing interface.
- Traffic lights with countdown timers: compare the signal and timer arrangement for the project.
- 300mm signal selection checklist: prepare the indication schedule, electrical version and installation details.
When requesting a supplier quotation, list the complete signal head, modules, brackets and controller separately. A nominal 300mm size does not specify the housing dimensions or establish controller compatibility. Send your selected model and drawing requirements to sky-sale@njgq.net.

Select the indication and complete assembly before requesting a quotation. A diameter identifies the optic size, not the housing dimensions, operating voltage or compatibility with an existing installation.
| Selection | Options to specify | Evidence to request |
|---|---|---|
| Signal indication | Ball, arrow, pedestrian, bicycle or lane control; aspect count and countdown if required | Selected model and approved signal schedule |
| Supply and control | Rated AC/DC input, controller output and countdown interface | Input rating, terminal drawing and compatibility review |
| Housing and installation | Material, orientation, bracket and cable entry | Dimensioned drawing and mounting arrangement |
| Optical and environmental requirements | Required performance classes and site conditions | Applicable model-specific test reports and configuration scope |
| Purchase scope | Module, complete head, brackets, controller and spares | Itemized configuration, quantity and packing details |
Review traffic signal size selection and the wiring checklist. Our workshop, packing and loading photographs show existing factory activity. Request the selected model’s specification and a quotation with your drawing, indication schedule, voltage, quantity and destination.
How to Select a 12-Inch (300mm) LED Traffic Light
300mm signal heads are commonly specified where a larger visual indication is needed than a 200mm unit. Select the signal face, lens type, voltage, mounting arrangement, and controller interface from the start so the delivered unit matches the installation.
Start with the application
- Vehicle approaches: ball, arrow, or combined indications.
- Pedestrian and bicycle crossings: dedicated symbols and optional countdown functions.
- Access, parking, and tunnel projects: choose the face arrangement for the operating rule.
Information for your RFQ
- Optic diameter, signal colours, and number of aspects.
- Operating voltage, controller type, mounting method, and local requirement.
- Project quantity and required delivery date.

Selecting a 300mm LED traffic signal
A 300mm LED traffic signal is commonly listed as a 12-inch signal. Check whether the selected item is a round vehicle signal, an arrow indication, a pedestrian display or a countdown unit. Nominal face diameter does not specify the total assembly dimensions. If replacing an existing unit, compare the housing, visor, mounting centres and electrical label. State the number of signal heads and the indication required in each head. A countdown display also needs its timing and controller interface confirmed; it should not be selected by dimensions alone.
