The user would use a POD if they are experiencing a socket issue that cannot be solved, if the precise replacement bulb for the set cannot be located, or if the user has a non-replaceable (sealed construction) LED light set.
Are the PODs supposed to illuminate like an actual light bulb?
The PODs will not illuminate. It does not mean that they are dysfunctional. They simply were not designed to do so. The POD is necessary for the repair of the LED set in order to maintain the electrical balance. Since the user did remove a LED from the set, more voltage is being forced upon the remaining functional bulbs.

This Item fixed the problem. My dogs chewed three light off of my tree. I didn't have any spare bulbs because they did it last Christmas too. These PODS fixed the section of the tree thyat the dogs damaged

Worked Great, We put up around 40,000 lights each year for Christmas and each year I have to replace around 10 -15 strands. This with my LED tool is going to save me a tremendous amout of money.
