Lighting - Failed Light

Sensor Verdict: The LCM sensor flagged the BLACK circuit (Clearance / License Plate) and this alert is assessed as a valid defect detection with 88% confidence. The technician confirmed through voltage testing and functional verification that the tag/license plate light was indeed faulty and not illuminating, directly corroborating the sensor's alert. The confidence is slightly below maximum due to the absence of TechAssist verification screenshots and limited photographic documentation.

Photo Evidence: Only one photo was submitted (BODY.jpeg), which appears to show a trailer electrical connector — likely a 7-pin round connector being inspected or handled by a gloved technician. While this may document a connector inspection step, it does not show the license plate/tag light before or after repair, does not show any other lights in the circuit illuminated, and does not include a clear nosebox wiring photo. There is no TechAssist app screenshot showing green 'Verified' status across all 5 circuits. The photo documentation is substantially insufficient relative to the required standard.

Vendor Compliance: The vendor (TA) partially followed the LCM troubleshooting procedure. Positively, the technician did use the Phillips Connect TechAssist app to perform a light check, which is a required step. However, compliance falls short in several key areas: no TechAssist completion screenshot was provided showing green 'Verified' for all 5 circuits, photos of each individual light illuminated were not submitted, and the nosebox wiring photo is either absent or limited to the single ambiguous connector image. The technician notes are also heavily fragmented and difficult to parse, indicating rushed or informal documentation practices.

Repair Summary: The technician removed the driver-side (DS) brake light assembly to gain access to the tag light connector, tested for voltage (confirmed present), diagnosed the tag light itself as faulty, removed and replaced the tag light, and reinstalled the DS brake light. The repair directly addresses the alerting BLACK circuit. No parts line items were submitted, which is a notable documentation gap — it is unclear what brand or part number of tag light was installed, making it impossible to verify compliance with approved/compliant light brands. Labor line items are also absent.

Key Concerns: Several concerns are flagged for this work order. First, the complete absence of parts and labor line items is a significant documentation deficiency that prevents cost tracking and parts compliance verification. Second, the photo package is nearly non-existent — only one connector photo was submitted versus the required set showing all lights illuminated and nosebox wiring. Third, no TechAssist 'Verified' screenshot was provided, which is a mandatory deliverable per the troubleshooting SOP. Fourth, the technician notes are poorly formatted and fragmented, suggesting the work order was completed hastily. Despite these concerns, the core repair logic is sound and the sensor alert appears to have been legitimately validated and resolved.
