LMR.com has the Shift lights & Warning lights for your 1979-current Mustang that are designed to let you look at the road without concentrating on your gauges! Shift lights are warning lamps fitted to vehicles in order to indicate to the driver that the maximum RPM has almost been reached. Ideally, a shift lamp will illuminate at the engine speed beyond that which delivers the maximum horsepower such that the horsepower before and after shifting is the same. This also increases safety for the driver by keeping his focus on the track at all times!
