Summary
[edit].jpg&action=edit§ion=1){kind=link}
| Description |
The top photo series show a vehicle headlight that was not on at the time it was shattered inward by a significant collision. Analysis of the low beam filament revealed that, despite the missing segment, it was still a uniform spring with the high beam element remaining intact. The tungsten was clean with no adhered glass particles, deformations or irregularities. In contrast, the bottom photos demonstrate a headlamp that was on at the time of the collision. Its element is extremely deformed and jagged, having balled up at each post. As the filament was hot at the time of impact, the inrushing oxygen reacted to form yellow-white tungsten oxide on both the low and high beam elements. Additionally, glass particles from the collision adhered to the hot tungsten. |
