Street, Drag, Race, Rally, Drift, Trials, Training… so many reasons why these displays are being used.

One question you should ask! Have you actually tried a progressive shift light? There are more benefits to them than most first realise.

“If you can’t see your tacho while driving, you don’t know what you are actually missing.”

It’s not about needing something to tell you when to shift.  Adrenalin flowing, red mist setting in, distractions, competitors, multiple engine noises… how much effort have you put in to getting there.  Are you going to get the most out of your engine and get the jump on the rest?

You can use the Shift-I as a reference to maintain performance targets, particularly when setting speed at corner entry and getting the right line for maximum corner exiting speed.  Obtaining and maintaining smooth and consistent laps times becomes increasingly important where endurance, fuel loads and tyres all play key rolls.  If you know what you can do and have a reference for what you've done, then you have a reference to maintain your best performance and improve upon.
