This paper aims to contribute to the understanding of automotive tinting popularity among car users in Malaysia. While comfort (heat and glare) and security stand among the main reasons behind the popularity, there is however, some notable safety arguments about the automotive tinting. The prevailing regulation on auto tinting, which is dubbed as “outdated and unfair”, had caused public uproar about the permissible limit in terms of Visible Light Transmission (VLT). The results from the most recent survey on automotive consumerism are used in the discussion, together with two previous MIROS’ studies i.e. on weather issues and the auto tinting consultation report to the Ministry of Transport Malaysia (MOT). The highlights, among others, were about the aftermarket behavior among car users in Klang Valley. Out of 265 respondents, approximately 70% of them had done the tinting to their current (main) car with the declared mean and maximum cost of MYR 780.81 and MYR 4,000.00, respectively. Also, the result has supported that the auto tinting together with the tires are the most popular aftermarket items for modification and retrofitting among the car users.
