Specify the required arrow indication
No individual arrow-board model cards are currently published in this category. For an enquiry, start with the required arrow direction and operating behaviour. A directional display, a flashing warning arrangement and a conventional traffic-signal arrow should be described according to the actual project requirement.
Provide the approved site layout and display sketch, including the viewing direction and available mounting space. If the indication must be switched by an existing controller, include its interface documentation. This allows the display and control requirements to be reviewed together instead of assuming compatibility from the arrow shape alone.
معلومات المشروع المطلوب تقديمها

- Operation: steady or specified flashing behaviour and how the command is supplied.
- Mounting and power: proposed support, available supply, cable route and service access.
- Order scope: number of units and whether controller, brackets, cables and spare parts are required.

Review the arrow from the approach direction
Show the intended arrow on a front-view sketch and mark the direction from which road users will see it. An arrow described from the rear of the equipment can be misunderstood during an enquiry. Use the same view when discussing the support position and the control command.
If more than one arrow or indication is required, list the permitted display states and whether any combination must be excluded. These are requirements for the project review, not functions to assume from a category name. Request the proposed artwork and connection description together before deciding whether an existing signal configuration or a custom enquiry is appropriate.
