There is no single price for a traffic light. The cost is set by the signal size, aspect count, housing material, controller, quantity and certification, so a useful budget starts with the configuration, not a catalogue number.
Main cost drivers
| Cost driver | Cheaper end | Higher end |
|---|---|---|
| Signal diameter | 100 mm / 200 mm | 300 mm / 400 mm |
| Aspect count | 1 or 2 aspect | 3 or 4 aspect with arrows |
| Housing | PC plastic | Aluminium / polycarbonate mix |
| Controller | Excluded | Included with cabinet |
| Quantity | Sample / small lot | Container / project volume |
1. Signal size and aspect count
Larger signal heads cost more because they use bigger housings, larger lenses and more LED modules. A 300 mm three-aspect signal costs more than a 200 mm two-aspect unit, and adding a fourth aspect or a 3-in-1 arrow increases the module and wiring count.
When comparing prices, confirm whether the quote is for the signal head only or includes the mounting bracket, visor, terminal block and any countdown display.
2. Housing material and lens
Housing material affects cost, mass, heat dissipation and durability. Compare the selected PC (polycarbonate) and aluminium enclosure designs using their actual dimensions, construction and test evidence; material names alone do not establish impact resistance or total cost. Lens design, any specified anti-fog treatment and UV stabilisation can also affect price and outdoor performance.
3. Controller and cabinet
A signal head alone is not a complete intersection system. The controller, conflict monitor, load switches, cabinet, detectors and cabling are separate line items. If the quote includes a coordinated or adaptive controller, the total will be much higher than a signal head quotation.
4. Quantity and OEM/ODM discounts
Order quantity and configuration can affect the unit price of LED traffic lights. A one-off sample price may differ from a project quotation. OEM and ODM choices such as a custom housing, lens or module can change tooling, testing and production costs; confirm repeat-order pricing and any minimum quantities in the quotation.
5. Certification and shipping
Required testing, certification or conformity assessment may affect project cost. Identify exactly which reports, declarations or markings the tender requires; EN12368 is a standard and CE is a marking, not interchangeable names for a certificate. Freight, customs and destination charges also affect landed cost. Ask the supplier to separate the ex-works equipment price, agreed compliance work and freight so quotations cover the same scope.
6. How to request an accurate quote
Send the signal diameter, aspect count, indication type, housing material, voltage, controller requirement, certification, quantity and destination. A marked-up drawing or signal schedule gives GAOQIAO everything needed to price the configuration correctly.
