I have used this popular light from FNM for only 6 days. Since the headlight area of my Hero Splendor bike is rectangular, the light spreads out. That's why I removed it and got a fog light.
Those whose headlight lens is rectangular like my Splendor are better off not taking it.
If it is like the headlight lens of bikes like Gixxer Monotone, Glamour, then you can take it.
