S.B. No. 1493 amends the Transportation Code by adding a new subsection regarding the requirements for high-mounted stoplamps on motor vehicles. Specifically, it states that a high-mounted stoplamp will be considered compliant with federal standards if it varies in intensity four or fewer times and does not deactivate for more than two seconds when the vehicle brakes. This change aims to clarify the compliance criteria for manufacturers and ensure that vehicles meet safety standards while allowing for some variability in stoplamp operation.

The bill is set to take effect on September 1, 2025, following its passage in both the Senate and the House with overwhelming support. The Senate approved the bill with a vote of 30-0, and the House followed with a vote of 138-3, indicating strong bipartisan agreement on the proposed changes to motor vehicle lighting equipment requirements.
