LED Keeper, LED Christmas Light Repair Pods, 4 Pods

Additional Pods (4) For Use With LED Keeper Repair Kit

Why would I use a POD?

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.
