It has not been commonly known that automotive exterior lights are safety devices and must comply with governmental regulations. Since the 1930s, the SAE Lighting Standards Committee has been actively working with the automotive industry OEMs, lamp makers, tier-two suppliers, and human factor experts to develop automotive lighting standards. These standards have been widely used or referenced by the U.S. federal or state governments in establishing and enforcing the lighting regulations.

Lighting Emitting Diode (LED), a new generation semiconductor light source often referred to as Solid-State Lighting (SSL), has been broadly adopted in illumination, display, visualization, and other areas due to its higher efficacy and longer life. LEDs, first introduced for automotive interior applications such as indicators, expanded to exterior applications including center high mounted stop lamps and other automotive signal lighting devices. Today, LED technologies are being used for night vision, occupancy detection, and many other automotive application areas.

Off-road commercial vehicles work for extended duration of time in the field on daily basis, typically more than 10-12 hours a day. Due to this, they need to spend substantial amount of time working in dark conditions in remote areas without compromising on efficiency and safety aspects. At such places proper lighting conditions are not available and off-road vehicles are bestowed with the task of fulfilling this need on their own. To secure safety, sufficient visibility is required around the vehicle. Due to their massive size and height, these off-road commercial vehicles need several high power work lights on each side of the vehicle to ensure flooding of the area around it with light thereby creating suitable working conditions for operator. Work lights consume high amperage of current. Higher the intensity of light higher would be the rating of the light in terms of wattage. Since, the battery voltage is fixed; it is the sinking current of the light that increases with wattage.

The current trend towards energy efficient commercial vehicles requires a substantial improvement in their aerodynamic performance. The two largest contributions to the drag of a tractor-trailer combination are the wake at the rear of the trailer and the turbulent in-flow at the trailer gap. By integrating into the design of the roof fairing ducts that divert and speed-up air flow it is possible to obtain a reduction of drag in the trailer gap and alter the trailer wake favorably. The resulting decrease in yaw-averaged overall drag coefficient is of 5.8%. This translates into an improvement in fuel efficiency of 3% when compared to the baseline . The design optimization was performed using parametric variation of a computational fluid dynamic model at zero and six degree yaw.

The performance of several aerodynamic technologies and approaches, such as trailer skirts, trailer boat tails, gap deflectors and gap reduction, was evaluated using track testing, model wind tunnel testing, and CFD simulation, in order to assess the influence of the design, position and combination of various aerodynamic devices. Scale model wind tunnel tests were conducted to have the best direct performance comparisons between several possible configurations. The track test procedure followed the SAE J1321 SAE Fuel Consumption Test Procedure - Type II. The wind tunnel tests were conducted on a 1/8 scale model of a tractor in combination with a 53-foot semi-trailer. The tests consisted of two phases: setting the initial baseline, and component testing of various configurations.
