it should be replaced immediately. This will extend the life of the remaining
working bulbs.
Leaving burnt out bulbs in the light set after a long period of time, will cause a
domino effect on the working bulbs. You might even notice the light set burning
much brighter. Eventually, all 50 bulbs in the same ring will burn out in and will
need to be replaced.
Please note that burnt out bulbs are not covered under
the warranty. They are considered normal wear and
tear and not a warranty defect.

How to repair an Incandescent light set?
Most individual light set failures are caused by a bulb not seated properly in its
socket or by a shunt failure.
 Shunt Failure
A shunt failure is a fail-safe feature below the filament of each bulb. The shunt is
activated when the filament burns out. This is what keeps the rest of the light set
illuminated. Occasionally, the shunt will fail causing the circuit to be broken and
the entire set to go out.
 Loose Bulb
If a bulb is loose, broken or not seated properly in its socket, the “flow” of
electricity from one bulb to the next is stopped causing the entire light set to not
light.
To check each bulb, take the following steps below:
1. Do not push in or twist the bulbs. Remove the first bulb in the strand.
2. Make sure the two copper wires are centered and not twisted before
positioning in socket.
3. If the set fails to light, continue this process for each bulb through the entire
set, removing the bulb and checking the copper wires.
How to repair an entire tree section?
If an entire section of your tree is not lighting (i.e. ALL of section A, or all of
section B, etc.), locate the plug of the light string for the section.
Plug that section directly into the wall outlet. If the section lights-up, continue to
use this section. Check the wiring harness from the section immediately below it
on the tree as it may be the cause of the problem.
If the section still fails to light, unplug and change the fuses in the light string (See
Figure 14). Slide the cover to the open position on the plug end of the light string.
