In a small workshop lined with aluminum insulation, the shrill buzz of tools fills the space as a shirtless man concentrates on a pair of Meta Ray-Ban smart glasses. Cans of compressed air, circuit boards, and wires clutter the workbench. The man, who goes by Bong Kim online, carefully disassembles the glasses, consults a sheet of notes, and returns to his task — removing one of the product’s key safety features: its recording indicator light.
Within minutes, Kim completes the modification. The glasses can still take photos and record videos as usual, but the small white LED — meant to alert people nearby that the camera is active — no longer turns on. The result is a pair of smart glasses capable of filming people without their knowledge.
Meta’s Push for Augmented Reality and Built-In Safeguards
Meta’s Ray-Ban smart glasses represent one of the company’s most visible efforts to bring augmented reality and wearable technology to everyday consumers. The glasses allow users to capture photos, record video clips, and stream content directly through Meta’s app.
To address privacy concerns, Meta included a white LED on the frame that automatically lights up during any recording. The system was also programmed to stop working if the light was covered or obscured — a measure designed to prevent covert recording.
But Kim’s alteration defeats that safeguard completely, allowing the glasses to function while the LED remains permanently off.
From Innovation to Invasion: Growing Public Concerns
The modification raises immediate privacy red flags. Without a visible indicator light, bystanders have no way to tell when someone is recording them. This concern is not theoretical — incidents of inappropriate filming have already been reported.
Earlier this month, the University of San Francisco’s Department of Public Safety warned students about an individual reportedly using Meta Ray-Ban glasses to record women on campus and share the videos online. Such behavior is already troubling, but disabling the LED removes even the minimal protection that signals recording is taking place.
Online forums such as Reddit, YouTube, and TikTok have become gathering spots for users seeking ways to bypass the LED. While some claim they want to record without distraction or to achieve “more natural” footage, others discuss openly voyeuristic motives.
According to 404 Media, which investigated Kim’s modification service, buyers of these altered glasses have been traced to states including California, Texas, and North Carolina, and even to international customers.
A Side Business That Bypasses Safeguards
Kim offers his service for around $60, promising to permanently disable the LED on customers’ glasses. For those who don’t already own a pair, he offers to purchase and modify them before shipping.
When 404 Media ordered a pair for testing, the only sign of tampering was a broken factory seal on the packaging. Once connected to Meta’s app, the glasses worked normally — except that the recording indicator light never illuminated.
Meta’s onboarding tutorial emphasizes the importance of respecting privacy and explicitly states that the LED light must remain visible to inform others when recording is active. However, Kim’s modification bypasses this entirely, allowing the glasses to record discreetly.
Testing Reveals the Extent of the Mod
404 Media’s tests confirmed that the external LED never turned on while recording or taking photos. A faint internal light appeared only inside the right arm of the glasses — visible only in dark conditions and only to the wearer.
Kim’s modification work appears well executed. The glasses functioned identically to an unaltered pair, showing no sign of external changes. Kim has demonstrated his process on YouTube, showing viewers that the LED no longer activates and thanking customers who purchase his service.
Several of his listings have since been removed from eBay, but payments for “Meta glasses service” have appeared on his Venmo profile, suggesting that sales continue through direct transactions.
Meta’s Official Stance: A Violation of Terms
Meta has stated that tampering with or disabling the LED violates its terms of service. The company insists the indicator light is central to its privacy framework.
According to Meta’s response to 404 Media, the LED is a safeguard designed to ensure transparency when recording. The company has reportedly increased the LED’s size from one millimeter to two millimeters to make it more visible and changed it from a blinking to a solid light. It also introduced tamper detection, which disables the camera if the LED is covered.
These measures were meant to address early concerns from privacy advocates, but Kim’s modification shows that even with upgrades, the system can be defeated through physical alteration.
