S.B. No. 1493 amends the Transportation Code by adding a new subsection to Section 547.323, which pertains to lighting equipment requirements for motor vehicles. The new language specifies that a high-mounted stoplamp will be considered compliant with current 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 high-mounted stoplamps in relation to federal regulations.

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, while the House passed it with a vote of 138-3, indicating strong bipartisan agreement on the proposed changes to motor vehicle lighting requirements.
