Where the Take (above) fails, the Rapid 3 light is a storming success.
Based on the venerable Cateye Rapid 3, the Fizik mount, in effect, costs a fiver (the regular light comes in at £19.99).
With its purpose-made clip, the Rapid is placed right behind and just below the saddle, meaning it’s well exposed to attract attention.
It’s unobtrusive and you can still use a regular saddle pack, so I can’t find a downside.
The Rapid 3 is an awesome light option - so good that if you're a Fizik saddle user, it's a must-buy, I'd say.
