The National Highway Traffic Safety Administration (NHTSA) has analyzed real-world crash data to determine if LED stop lamps and center high-mounted stop lamps are more beneficial than incandescent lamps at preventing rear-impact collisions. The data was inconclusive when considering other factors, such as vehicle redesign and a change to the rear-lighting configuration. The NHTSA will continue to review future crash data in case it provides more guidance on whether there is a measureable difference.
