  pulsating light systems for high-mounted stop lamps, and for other 
                               purposes.

SEC. 2. REAR-END COLLISION AVOIDANCE SYSTEMS.

    (a) Definitions.--In this section:
            (1) Pulsating light system.--The term ``pulsating light 
        system'' means a system for a high-mounted stop lamp in which--
                    (A) when the brake of the vehicle is applied, the 
                lamp pulses rapidly not more than 4 times and for not 
                more than 1.2 seconds, after which the lamp converts to 
                a continuous light as a normal stop lamp until the time 
                the brake is released; and
                    (B) the pulses described in subparagraph (A) may 
                not repeat on a subsequent application of the brake of 
                the vehicle for a lock-out period of at least 5 seconds 
                after the release of the brake described in that 
                subparagraph.
            (2) Standard 108.--The term ``Standard 108'' means Federal 
        Motor Vehicle Safety Standard Number 108, contained in section 
        571.108 of title 49, Code of Federal Regulations (or a 
        successor regulation).
    (b) Clarification on Pulsating Light Systems.--Beginning on the 
date of enactment of this Act, Standard 108 shall be deemed to allow 
for the use of pulsating light systems on vehicles covered by Standard 
108.
    (c) Rulemaking.--Not later than 180 days after the date of 
enactment of this Act, the Secretary of Transportation shall promulgate 
such regulations as are necessary to update Standard 108--
            (1) to include performance-based standards for pulsating 
        light systems; and
            (2) to allow for the use of pulsating light systems on 
        motor vehicles covered by Standard 108.
