The run has 2 torch lights and 3 path lights. It has been fine for about 6 months. The one closest to the slim line transformer set to dusk to dawn turns off for about 15 seconds or so then turns back on for several minutes and repeats. What should I be looking for? I am using Volt 16/2 cable & VOLT® 5W Single Source LED MR16 (30 Watt Halogen) Thanks for any help.
