Real customer cases， witness our professional service and commitment
Saudi customer *** purchased a total of 20,000 sets of truck trailer LED combination tail lights (model ***) from our company, shipped in two batches. After the second batch of 10,000 sets arrived at the port, the customer reported that sampling inspection found approximately 3,500 sets with the following quality issues: 1) The red lens and base had obvious color deviation, inconsistent with the first batch of confirmed samples; 2) Some lights showed internal water ingress during simulated rain testing, causing LED beads to short-circuit and fail. The customer requires full return and compensation for related customs clearance and warehousing losses.
The company immediately arranged for quality engineers to connect with the customer via video to confirm the issue, and requested the customer to return the faulty samples for failure analysis. After testing, it was confirmed that the problem originated from the supplier changing the batch of red PC raw material during the second production run, and the sealing adhesive application process parameters for the tail lamp housing were not adjusted in time. The company has taken the following measures accordingly: 1) All 10,000 sets of lamps already at port were returned, with the company bearing the return shipping costs and related port charges at the Saudi destination; 2) An emergency backup sealing process plan was activated, and 8,000 sets of improved products were re-manufactured and expedited by air freight to Saudi Arabia, with third-party inspection reports attached; 3) The customer's storage fees, customs late fees, etc., totaling *** USD, were directly deducted from the payment as compensation; 4) Internal accountability was pursued against the supplier, incoming material inspection standards were re-reviewed, and a 100% air-tightness testing process was added.
After receiving the replacement batch of new products, the customer randomly inspected 100 sets on-site for rain and color difference comparison, and all passed. The customer agreed to continue cooperation and maintain the delivery date for the remaining third batch of the original order. Our company bore losses of approximately *** USD from the return and reshipment, but retained the long-term cooperation with this major Saudi customer. Subsequently, the customer placed a trial order for an additional 50,000 sets of automotive LED work lights.
A major truck assembly plant customer in the Middle East (customer name: ***) purchased 50,000 sets of LED combination tail lights for truck trailers (model: ***) in one order. After delivery and installation, about 15% of the lights were reported to be non-illuminating, dimly lit, or flickering, seriously affecting the vehicle production schedule. The customer demanded immediate resolution, otherwise they would file for return and compensation claims. Due to time zone differences and on-site constraints, engineers could not be dispatched immediately, so remote diagnosis and resolution were required as quickly as possible.
We immediately activated our remote technical support protocol, arranged for senior engineers to establish a video link with the customer's on-site technical team, and guided them through step-by-step troubleshooting using basic tools such as multimeters. The specific steps are as follows: 1. Randomly selected 10 defective lamps for individual power supply testing to confirm that the lamps themselves were not damaged; 2. Inspected the vehicle wiring harness interfaces and found that some vehicles, due to the use of non-standard 7-core/15-core adapter cables, had crossed signals between the turn signal and brake light; 3. Remotely sent standard wiring diagrams and voltage testing procedures, guiding the customer to replace connectors with SAE J560-compliant plugs and unify the ground wires; 4. Measured the socket voltage on all 5,000 installed vehicles one by one and corrected all incorrect wiring on site; 5. Simultaneously provided an English version of the "Batch Installation Self-Inspection Manual" and video operation guides for the customer's quality control department to conduct subsequent spot checks.
With remote guidance, the customer completed troubleshooting and correction of all lamp wiring within 48 hours and restored normal operation. No similar faults occurred in subsequent batches. The customer acknowledged the response speed and professionalism of technical support, and placed an additional order for 20,000 sets of LED work lights and accessories. This remote support effectively avoided a return loss of approximately 1.8 million RMB, while also consolidating the long-term cooperative relationship between both parties.
