In developing and evaluating automobile parts, the environmental conditions of automobiles are the most important. In particular, in the case of exterior lamps, the development standards are very different depending on the environmental conditions of the vehicle because consumers can directly respond to parts conditions under both thermal stress from the engine and vibration stress from the vehicle body. Therefore, with the recent expansion of electric vehicles, advantages and disadvantages arise by applying the test conditions of internal combustion engines when developing parts. For example, in terms of thermal conditions, it is advantageous because there is no engine heat, and in terms of noise, it is disadvantageous because there is no engine noise. In terms of vibration, the structure and weight of the vehicle are different compared to vehicles of the same class, and the characteristics are different. Therefore, by re-researching and applying these conditions for lamps dedicated to electric vehicles, it is possible to bring cost advantages and prepare for consumer claims in advance. In this study, the environmental conditions of exterior lamps for these electric vehicles are reanalyzed and product development direction and test evaluation method that can be differentiated from internal combustion engines is proposed.
