YakAttack has a 4 LED Module for VISI lights. Replaces the stock 2 LED found in the VISICarbon Pro and VISIPole II.
I ordered one and swapped it out for my 2 led module and tried it out first time last night.
Does not noticeably light up the inside of the kayak but the light at the top of the pole is much brighter.
I am frequently out on the lake after dark and this should really help with others being able to see me.
If I forget my headlamp or forget to charge it and need a light to untangle something, believe that if undo the pole in middle should have plenty of light to do that also. The 2 led module did not put out enough light for this.
