2. Plastic headlight restoration - Wikipedia

   en.wikipedia.org/wiki/Plastic_headlight_restoration

   Headlight restoration or plastic headlight restoration is the act of restoring aged headlight lenses that have become discolored or dull due the original factory UV protective coating degrading primarily due to UV light and other environmental factors such as road debris impact (stones, sand, etc.) rain, and exposure to caustic chemicals.

3. Federal Motor Vehicle Safety Standard 108 - Wikipedia

   FMVSS 108 is codified in Title 49 of the Code of Federal Regulations Part 571, Section 108. [1] The most recent version was published by NHTSA for comment in December 2007, [2] and since then, it has been amended in April 2011, [3] August 2011, [4] January 2012, [5] December 2012, [6] December 2015, [7] February 2016, [8] and February 2022.

   The colour coating has started to flake off this PY27/7W bulb, a relatively new problem. The amber bulbs commonly used in turn signals with colourless lenses are no longer made with cadmium glass, since various regulations worldwide, including the European RoHS directive, banned cadmium because of its toxicity.

5. Headlamp (outdoor) - Wikipedia

   en.wikipedia.org/wiki/Headlamp_(outdoor)

   A headlamp, headlight, or head torch is a light source affixed to the head typically for outdoor activities at night or in dark conditions such as caving, orienteering, hiking, skiing, backpacking, camping, mountaineering or mountain biking.

6. Optical coating - Wikipedia

   Another type is the high-reflector coating, which can be used to produce mirrors that reflect greater than 99.99% of the light that falls on them. More complex optical coatings exhibit high reflection over some range of wavelengths, and anti-reflection over another range, allowing the production of dichroic thin-film filters.

7. Anti-reflective coating - Wikipedia

   en.wikipedia.org/wiki/Anti-reflective_coating

   The layer is then called a quarter-wave coating. For this type of coating a normally incident beam I, when reflected from the second interface, will travel exactly half its own wavelength further than the beam reflected from the first surface, leading to destructive interference. This is also true for thicker coating layers (3λ/4, 5λ/4, etc ...

8. High-intensity discharge lamp - Wikipedia

   en.wikipedia.org/wiki/High-intensity_discharge_lamp

   Phosphor Coating: Some HID lamps, like Mercury Vapor lamps, also utilize phosphor coatings on the inner surface of the arc tube. These phosphors absorb the ultraviolet (UV) light emitted by the excited gas atoms and then re-emit visible light. The combination of UV light and the emitted visible light creates a broader spectrum of colors.

9. UV coating - Wikipedia

   en.wikipedia.org/wiki/UV_coating

   UV coating can be applied via most conventional industrial coating applications as well as by silkscreen and 3D printing. [ 8 ] Due to the normally high solids content of UV coating/varnish the surface of the cured film can be extremely reflective and glossy. 80 lb text and heavier weights of paper can be UV coated, however, cover weights are ...
