Amber has been scientifically proven to be easier to notice, and mildly safer than using the same bulb as the brake light to indicate a turn.

Here’s a paper on it. crashstats.nhtsa.dot.gov/Api/Public/…/811115

This paper contains data relating to the effectiveness of amber turn signals by comparing striking and struck cars with the same configuration (amber or red), and the odds of not getting struck with an amber turn signal equipped vehicle is always about 4-8% better than otherwise.

Thanks for this. I see so many people here talking like it’s obvious, but I’ve never been confused by a turn signal. I’m curious to read this.

  Unless you have some kind of color blindness, orange is among the most noticeable colors to the human eyes, especially in an urban background

    it more just the training, from 20 plus years of driving, and looking out for red and orange but yellow colors.
