Please make sure that the second end point is away from you, so that you can avoid & safe from electric shock. Then switch on the power box. With the help of tester, you can check the second end point of set, whether the power is passing or not.

Once you find fault bulb, remove it then joint the remaining bulbs. You can also use the soldering iron to joint them strongly then insulate it by using insulation tape. After that, again prepare the two sets of lights, each having at least 15 or more. Then connect the 2 sets to neutral wire.
