I have a tree with 10 strings of 50 lights. I inject power at the end of the tree. The string in the second position blinks constantly and any lights beyond that also blink. If I connect only string 1 and 2 ,the first string lights ok and about 10 lights of the second string but there on blink.
Could I have a bad light and can I cut out and replace a bad light to eliminate my problem.
