Abstract
This study was requested by INDOT to determine if current lighting packages used on INDOT maintenance vehicles, specifically snow plow vehicles, can be improved with other commercially available products. Different light products were obtained from various vendors, mounted on INDOT vehicles, and visual comparisons were performed under various lighting and weather conditions by a team of observers. The comparison evaluations were performed revealing that other light packages, LED models for most options, were brighter and certain colors more visible. The preferred light models are recommended. These recommendations were forwarded to appropriate individuals that make these decisions at INDOT. Implementation is dependent on purchasing decisions made at the Central Office and at each of the Districts.
