The TIAA MRT EMU's lighting system includes interior lighting, emergency lighting, front escape door lighting, cab lighting, cab reading lights, headlights, taillights and exterior indicators in commuter trains. In addition to the above lighting equipment, passenger reading lights are installed in express trains. The EMU's lighting systems are customized and modularized design and consist of features including high reliability and maintenance-friendly.
For the interior lighting of the EMUs, there are two rows of embedded fluorescent lamp in the ceiling of each EMU coach. Additionally, emergency lighting systems are distributed near exits and the front escape door lighting is also installed for safety concerns. The emergency lighting can maintain function for 45 minutes during emergency escape. One row of embedded fluorescent lamp, reading lights and emergency lighting are installed in the cab. As for the reading lights in express trains, they are set above each seat and can be controlled from the switch in passengers' armrests, providing passengers a comfortable reading environment.
EMU headlights and taillights are set in the front of the cab. The headlight is made of stainless steel structure which can prevent moisture infiltration and provide an illumination distance of 35m from the cab. In bad visibility conditions, the illumination distance of headlights can be manually adjusted to 50m. The light beams of the headlights can only be adjusted externally. The taillights consist of a protection cover and a LED illumination unit which can also prevent moisture infiltration. During daylight conditions, the taillights can be clearly identified 300m away from the cab. An exterior indicator unit, which is inclusive of a red door warning light and an amber exterior warning light, is installed on each side of the coach.
Overall, the interior lighting system of EMUs adopted energy- conserving T5 lamps to provide passengers a comfortable ride and bright environment.
