4 Aspect Led Traffic Lights – China LED Traffic Light Manufacturer

Define the fourth section before choosing the assembly

The four-section catalogue includes combinations of ball indications, directional arrows and countdown functions, together with spare housings. A fourth section can serve a different purpose in each configuration. Describe that purpose explicitly so the quoted assembly matches the intended signal layout.

Use a front-view drawing to label each section and its required colour or symbol. Where the display includes more than one arrow, show the direction and control requirement for each. For an existing installation, compare the complete enclosure dimensions and support arrangement instead of assuming a longer head will fit the original brackets.

需确认的信息

• Confirm whether the quotation includes optical modules, wiring, terminals, visors and mounting hardware.
• Identify each controller output or interface needed by the proposed indication arrangement.
• Check clearance and access for maintenance around the complete four-section head.
• If ordering a replacement body, match the original module dimensions, seals and fixing points before confirming the part.
