Cool T/O aborted close to V1 due to warning light - you sure ?!

A typical briefing prior to departure would include something like:

"...... above 80Kts and prior to V1 we only will stop for the following: any fire warning, an engine failure identified by at least two parameters, a configuration warning, a control difficulty, a blocked runway, a predictive windshear warning, or anything that the Captain thinks might jeopardise safety"

Now three of those stop items (fire, configuration, windshear) generate an aural warning, and engine failures tend to generate a rather noticeable yaw (i.e. and as such it is covered by the 'engine failure' and 'control difficulty' reasons to stop).

Normally above 80Kts, one doesn't stop for 'Master Caution' annunciations - unless, in the Captains judgement, it is preferable to do so - i.e. the closer you get to V1 the more orientated one becomes towards 'Going' rather than stopping.

So one would imagine that it was a bit more than just a 'warning light' that prompted them to stop if indeed they were close to V1 as has been suggested.

Veritably, one of life's great debates is the stop / go decision process.
