This document specifies that black is the only color that can be used for the insulator at the bottom of the base of T-1 and T-1 ¾ Flanged Base lamps.
This SAE Aerospace Recommended Practice (ARP) provides criteria for design and location of power supplies, controls, light fixtures, and associated equipment which are used to provide emergency illumination in transport aircraft, designed to comply with 14 CFR Part 25 (see Reference 1) for operation under 14 CFR Part 91 (see Reference 11) and 14 CFR Part 121 (see Reference 2), and also in compliance with FAA Advisory Circulars AC 25.812-1A (see Reference 3) and AC 25.812-2 (see Reference 10). It is not the purpose of an ARP to specify design methods to be followed in the accomplishment of the stated objectives.
“Day & night marking” is used in automobiles, aviation, instrumentation and computer keyboards to make buttons and controls (e.g. door locks, window controls, sound system adjustments, etc.) clearly visible under ambient illumination conditions varying from bright sunlight (day) to low light (night). Although it sounds simple, manufacturing these products cost-effectively in a small-batch production environment requires the use of a sophisticated, automated, laser-based tool.
In recent years, research on Human Computer Interaction (HCI) based on emotion recognition using behavioral and physiological signals have attracted immense interest in research circles. Lighting inside the automotive make us feel differently about our driving and how we feel or behave. From the literature, it is observed that ambient lighting makes an impact on the driving experience and it delivers an emotional atmosphere inside the automotive. Driving fatigue can be reduced if the lighting is controlled properly. These days, ambient interior lighting can be considered to be the point of fashion for high end automotive and also impact driver’s mood and comfort. There are different types of automotive based lighting automation systems available but emotion based control is in early or nascent stages of research. Speech controlled light control systems, control the light by the recognition of speech of the user and by using facial expressions lighting can be controlled. Facial/speech signals consist of both outward physical expression and the inborn emotions. These emotional signals thus exhibited vary from situation to situation and are mostly dependent on the conditions. In this work, we attempted an emotion based interior lighting control. Based on the emotions observed through the Emotion Recognition System (ERS), the lighting can be modified in a predefined fashion. In the proposed ERS, five types of emotions are considered, like happy, sad, angry, neutral and disgust. Live image expression and voice data of the driver/passengers are considered as inputs to the system and based on the output from the ERS, interior lighting is controlled. Standard databases are used for training ERS system. The proposed algorithm is tested, and the results demonstrate the approach and the reliability of the method to obtain the solution for lighting control. Machine Learning methods like Convolution Neural Networks (CNN) are used for classification of features in ERS system.
The Body Control Module (BCM) is a very large integration site for vehicle features and functions (e.g., Locking, Alarms, interior lighting, exterior lighting, etc…). Every few years the demand to add more feature/functions and integrate more vehicle content increases. The expectation of the 2013 MY (model year) BCM, was to double the feature content and use it globally. The growth in 3 years of feature/function content was huge number that grew from 150 to over 300. This posed a major challenge to the software development team based on the methods and process that were deployed at the time. This paper cites the cultural and technology changes that were overcome when Ford Motor Company partnered with Tata Consultancy Services to help manage and define this new software engineering development methodology. The process of getting from a vague description of a new body module feature to a saleable product, presents several very challenging problems.

Automotive exterior lighting systems has several regulatory requirements & most of the manufactures have defined internal standards to achieve desired expectations based on vehicle category. Unavailability of such requirements for interior light illuminating systems has motivated the authors to generate test specifications & measurement methodology. There has been growing interest in automotive vehicle interior lighting for both functional and aesthetic requirements. The purpose of this study is to evaluate the Interior light illuminating devices in terms of “Light harmony”. The lighting harmony is “Maintain the color combination and light intensity level within users comfort zone”. In this study the lighting harmony is measured by means of two methods; one is Subjective evaluation & other is Objective evaluation. The details of these methods are discussed & the available results were analyzed to understand the acceptable limits of light intensity & color combination to achieve expected harmony. Subjective evaluation is the judgmental methodology to identify the harmony. The results give border view to take judgmental decision. Objective evaluation is carried out using CCD based illumination measurement system to get a clearer understanding of luminance and color, which gives the minute details about each aspect of harmony.
While functionality cannot be compromised inside heavy trucks, their cabs increasingly mesh practicality with passenger-car sensibilities for comfort and ambience. “There's no storage!” a woman said rather incredulously to her husband, surveying an interior concept on display in a supplier's booth at the recent Mid-America Trucking Show (MATS) in Louisville, KY. “It's a show truck, hon,” he replied. “It's supposed to look pretty, not be functional.”
Thin films and vacuum technology are used frequently throughout advanced, environmentally friendly automobile manufacturing. From automotive light-weighting of conventional ICE automobiles, to hybrid and EV manufacturing, thin films deposited in vacuum systems, vacuum heat-treating, and vacuum leak testing are a major part of automotive device, component and sub-assembly manufacturing. Starting with new applications of polycarbonate glazing by plasma coating, which provides lower CO₂ emissions, greater design freedom and cost reduction through parts consolidation. For high-strength, light-weight automotive steel stampings used in chassis and body parts, wear-resistant coatings are applied in vacuum systems to provide wear protection and to extend the stamping die lifetimes. Thin film vacuum equipment is also used for the manufacturing of: control circuits, film capacitors (EVs, PHEVs and HEVs), power ICs (hybrids), sensors (air bag, tire pressure, etc.), secondary batteries (EVs), coatings for mirrors, interior lighting, lamps (LEDs and reflectors), front grilles, touch-screen displays used in navigations systems, and gauges. Vacuum brazing is used to fabricate automobile radiators and air conditioners. Vacuum leak-testing is used to test the integrity of a wide-array of components, from tire rims and heat exchangers, to transmissions, braking systems, airbag inflators, and torque converters. This paper will elaborate on the vacuum equipment and processes used in advanced, in-vehicle product solutions.
