LED Traffic Signal Light Manufacturer | 100mm, 200mm & 300mm – China LED Traffic Light Manufacturer

Compare 300 mm and 400 mm configurations with the same purpose

Many entries here appear as 300 mm and 400 mm versions of a related signal arrangement. Use this page to compare the configuration needed by the project: bicycle, pedestrian, U-turn, arrow, ball indication or an integrated timer. The diameter alone does not determine whether a model fits the approved signal layout.

Choose the required indication first and then compare model-specific drawings and electrical data for the shortlisted sizes. Existing brackets, available installation space and controller connections should be checked again when changing size. A larger front face does not establish a particular visibility distance or approval for every road.

Checks for models on this page

• 300MM(12英寸) 3灯头红黄绿圆形满屏LED交通信号灯，带倒计时: confirm the timer interface as well as the three-colour signal sequence.

Keep the selected product links in your enquiry so the configuration is unambiguous. Send the relevant drawings and required quantity through the contact page; the final quotation should identify the exact model and included components.
