BibTeX does not have the right entry for preprints. This is a hack for producing the correct reference:
@booklet{EasyChair:2637,
author = {S. P. Rishab Jain and Deeksha Dayanand and C. L. Gowthami and K. M. Punith},
title = {Vehicle Movement Street Light Controller System},
howpublished = {EasyChair Preprint 2637},
year = {EasyChair, 2020}}
