Identified by its "Black Light", the BLITZ BLM (Black Light Meter) Racing Meter is the only gauge on the market featuring the unique black light illumination. Featured in a carbon face and chrome bezel, a black light bulb is installed in the front of the gauge; this process gives the meters a purplish fluorescent glow on the BLITZ logo. The BLITZ BLM Racing Meters are available in boost, oil/water temperature, oil/water pressure, and exhaust temperature. (Available only in 60mm, all gauges include necessary hardware and sensors.)
