2. Emergency vehicle lighting - Wikipedia

   en.wikipedia.org/wiki/Emergency_vehicle_lighting

   Emergency vehicle lighting, also known as simply emergency lighting or emergency lights, is a type of vehicle lighting used to visually announce a vehicle's presence to other road users. A sub-type of emergency vehicle equipment, emergency vehicle lighting is generally used by emergency vehicles and other authorized vehicles in a variety of ...

3. Light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode

   Main article: Light-emitting diode physics. In a light-emitting diode, the recombination of electrons and electron holes in a semiconductor produces light (be it infrared, visible or UV), a process called "electroluminescence". The wavelength of the light depends on the energy band gapof the semiconductors used.

4. ISO standards for trailer connectors - Wikipedia

   en.wikipedia.org/wiki/ISO_standards_for_trailer...

   Trailer connectors between the trailer and passenger car, light truck or heavy trucks with 12V systems. In Europe, both 7-pin (ISO 1724) and 13-pin (ISO 11446) are common. The 13-pin version being phased in is newer, provides more services than the 7-pin, a more positive locking and also better protection against moisture and contamination.

5. LED strip light - Wikipedia

   en.wikipedia.org/wiki/LED_strip_light

   An LED strip, tape, or ribbon light is a flexible circuit board populated by surface-mount light-emitting diodes (SMD LEDs) and other components that usually comes with an adhesive backing. Traditionally, strip lights had been used solely in accent lighting, backlighting, task lighting, and decorative lighting applications, such as cove lighting.

6. LED street light - Wikipedia

   en.wikipedia.org/wiki/LED_street_light

   An LED street light is an integrated light that uses light emitting diodes (LED) as its light source. These are considered integrated lights because, in most cases, the luminaire and the fixture are not separate parts. In manufacturing, the LED light cluster is sealed on a panel and then assembled to the LED panel with a heat sink to become an ...

7. SMD LED - Wikipedia

   en.wikipedia.org/wiki/SMD_LED

   The light from white LED lamps and LED strip lights is usually provided by industry standard surface-mounted device LEDs (SMD LEDs). [1] Non-SMD types of LED lighting also exist, such as COB (chip on board) and MCOB (multi-COB). Surface-mounted device LED modules are described by the dimensions of the LED package. A single multicolor module may ...
