The shift light sequential from Omex is based on the systems used in Formula 1 and BTCC. The shift light sequential features four high power colour LEDs in an external module which light incrementally as you approach the shift point. These LEDs can be programmed to light at intervals of between 0 and 600 RPM per LED from the shift point. The shift point can be set from 2,000 RPM to 20,000 RPM on 2 cylinder, 4 cylinder and distributor-less ignition systems, 12,000 RPM on 6 cylinder and 10,000 RPM on 8 cylinder.  All Omex microprocessor based shift lights and rev limiters feature Omex's acclaimed method of calibration. Shift point and rev limit is set independently of the car's tachometer, thereby removing any instrument error by incrementing in steps of 100 RPM by simply pressing a button on the unit. Precise digital timing ensures response within one engine revolution.
