Low Pressure Hydraulic Brake Light Switch Street Hot Rod 45PSI Activation, 1/8" NPT Universal Port Fit for Ford & Mopar Vehicles, Universal Brake Systems

Our redesigned hydraulic switch activates brake lights at 45PSI (vs. legacy 95PSI models) through precision-calibrated internal springs, achieving 22ms response times for modern driving safety requirements . The normally open design closes circuits at optimal pressure thresholds to prevent premature bulb wear.
