What to do if the warning light stays off for a long time?

Warning lights are crucial components in road safety facilities and personal protective equipment. For high-quality warning lights manufactured by Ningbo Hoyoung Safety Products Co., Ltd., if the light remains off for an extended period, please refer to the following professional troubleshooting steps:

1. Check Power Connection and Fuse

First, check if the warning light's power connection is normal. This includes checking if the battery has power, if the plug is loose, and if the fuse is blown. Power problems are the most common reason for lights not working.

Solution: Replace the battery, check and reconnect the power cord, or replace the damaged fuse.

2. Check the Bulb or LED Light Source

Warning lights usually use high-brightness LED beads. If the LED beads are aging or damaged, the light will not function properly.

Solution: Open the light fixture and check if the LED beads show obvious blackening or cracking. If necessary, have a professional replace the bulb or LED light source.

3. Check the Circuit Board or Wiring

After long-term use, the circuit board inside the warning light may have broken circuits due to moisture or corrosion.

Solution: Observe the circuit board for signs of discoloration or corrosion. If any abnormalities are found, please contact a repair technician for professional repair or replacement.

4. Confirm if the Light Fixture is Damaged

Check the light fixture body for any obvious cracks or damage. Damage to the casing may cause internal components to fail.

Solution: If the light fixture casing is damaged, please contact the after-sales service center of Ningbo Hoyoung Safety Products Co., Ltd. for replacement.

Note: If none of the above methods solve the problem, it is recommended to immediately contact the after-sales customer service of Ningbo Hoyoung Safety Products Co., Ltd., and stop using the faulty light fixture to avoid affecting safety.

What do red, yellow, and green lights represent?

In traffic safety facilities, red, yellow, and green lights are the most basic signal light colors, each conveying clear instructions.

1. Red Light

A red light represents "no entry," the strictest signal.

Meaning: Indicates that the road or area is closed to traffic, and you must stop immediately. Behavioral Guidelines: At traffic intersections, vehicles and pedestrians must strictly obey the traffic signals; running a red light is strictly prohibited.

2. Yellow Light

The yellow light represents "caution" or "warning," serving as a reminder to be attentive.

Meaning: It indicates that the traffic signal is about to change (e.g., from green to red), reminding drivers to slow down.

Behavioral Guidelines: If you have already entered the intersection and cannot stop safely, you may continue; if you have not yet entered, you should prepare to stop.

3. Green Light

The green light represents "permission to proceed," and is the most positive signal.

Meaning: It indicates that the road is safe to proceed, and vehicles may pass.

Behavioral Guidelines: Even when the green light is on, you still need to observe the intersection carefully and ensure safety before proceeding.
