What types of equipment are specifically forbidden on passenger cars in Texas?

In Texas, it is specifically prohibited for passenger cars to have a red light visible from the front. This regulation exists because red lights in the front of a vehicle are typically reserved for emergency vehicles. The presence of such lights could lead other drivers to mistakenly believe that the vehicle is an emergency vehicle, potentially causing confusion or dangerous situations on the road.

The other types of equipment mentioned are either legal or not expressly prohibited for passenger vehicles in Texas. For example, satellite radios and backup cameras are commonly found in many modern cars and serve as entertainment and safety features, respectively. Sunroofs are also permitted as they enhance passenger comfort and can improve the driving experience. Thus, the regulation regarding the red light focuses on maintaining clarity and safety on the roads by limiting the use of certain indicators that may mislead other drivers.
