Speed System

With the shift light on a remote lead, only the shift light itself needs to be on the dashboard; vital in small single seat race cars with tiny dashboard areas and ideal for a hidden ‘factory’ look on road cars.

Protect your engine.

If you make a mistake and miss a gear, the Speed System protects your engine from damage caused by over-revving. At a user definable engine speed, an ignition cut rev limit reduces engine power safely to limit the engine speed.

Digital Set
Omex's acclaimed digital setting method using increment and decrement buttons and LEDs allows the user to set the shift light rpm in 100rpm steps. This does not rely on external information and so removes error due to tachometer and reading inaccuracies.


Over 25 years of shift light and rev limiter design and manufacture, and thousands of units being used all around the world are real proof of Omex’s design and build quality.

UK ISO9000 built

All Omex products are manufactured in the UK in an ISO9000 certified factory and are individually tested before sale, ensuring a consistently high quality product.


The unit is epoxy filled giving it extreme resistance to vibration, shock, and water, giving a long life even in the most demanding motorsport environments.

European Type Approved

The Omex product range has been tested in a government authorised test centre proving resilience to (and low transmission of) electromagnetic interference.

Make the most of your engine’s power.

Shift gear too early and you not only miss out on the power at the top of the rev range but also drop to a lower engine speed that is below the optimum torque band making acceleration slower after the gear shift. Shift gear too late and you can hit the rev limiter or run the engine where the power is dropping off, wasting valuable tenths of seconds.

Perfectly timed shifts.

Trying to watch the vehicle’s rev counter to make these gear shifts takes your concentration away from the many other things you need to look at when driving. The Speed System’s large bright LED gives an unmissable visual indication to give you perfectly timed gear shifts, every time. Multiply these gained tenths of seconds per gear shift over an entire race, rally stage, sprint or hillclimb and you have found the difference between losing and winning.

Adjustable in steps of 100rpm

Accurate to +/- 10rpm @ 6,000rpm
