You won't need two leak lights unless you're leaving them in two different locations. I have a white leak light that works well enough. I'm assuming you're the otherside of the pond so I suggest trying amazon. I prefer letting my tech sort out my saxes, which reminds me I need to book mine in sometime this year!!Anyone have suggestion for a super cheap diy leak light? I'm looking at the LED ropes but they seem to be upwards of $20 each and if I need 2 that doubles the price. Also, if the ropes are the way to go, is there a cheaper place and do i get white or blue leds ?
