🔦 Public Notes – Plain Language Explanation
Device Tested: J.W. Speaker 8700 Evo-X LED Headlamp (x2)
Date Tested: June 6-13, 2026
Part Number: 0562241
Standard Referenced: FMVSS 108
❌ Low Beam – FAIL
• Slightly too bright at a high upward angle, which increases light scatter in fog, rain, or snow.
• Not bright enough at an upper right-side region, just above the cutoff, reducing right-side sign visibility at 50-100 m.
❌ High Beam – FAIL
• Not bright enough far off to the left at distance, reducing wide-beam coverage toward the roadside.
❌ Color Test – PASS
• Color measurements for the parking light were outside the white zone, producing a beam shifted into the green region.
⚠️ Disclaimer
Any failed test points shown in this summary may pass in official compliance testing. FMVSS 108 allows a 0.25° re‑aim at each test point, but we do not apply that allowance in our testing, so results can appear slightly stricter.
🔍 What I Noticed During the Test
Both samples showed a small shadowed area near the center of the beam, just below the kink and left of the V-line, with a slight reduction in brightness.
