Apart from my jerseys i'm rolling in predominantly black, so i'm looking to further reduce some risk on the road and so motorists can see me well ahead. Does anyone have or know of a tail light that is well visible during the day? How many lumens is required for a car to see you? I'm currently looking at these:

Knog Blinder R, 70 lumens, looks streamlined, good features. Knog - Blinder Road R Bike Light

Lezyne Micro Drive Rear, adjustable, looks...weird Lezyne - Engineered Design - Products - LED Lights - Micro Drive (Rear)

Also found the Dinotte Quad Red @ 200 lumens (necessary?) but at $243 she's a bit steep.

Cheers
