A tracer lamp unit for use with a DSX system is disclosed herein. The tracer lamp unit includes an elongate housing with a generally rounded cross section wherein the housing is configured to be secured within an opening defined by a piece of telecommunications equipment and held within with a press-fit, wherein the housing provides structural support for a lighting arrangement including a lens, a capacitor, a resistor, leads, and a flashing control circuitry, the housing further providing structural support for spring members including tail portions and electrical contact portions, wherein the electrical contact portions engage the leads to provide an electrical connection therebetween. In another embodiment, the tracer lamp unit comprises an LED flashing module that houses a lens, a capacitor, a resistor, leads, and a flashing control circuitry, wherein the tracer lamp unit housing is adapted to slidably receive, provide structural support for, and be separable from the LED flashing module.
