Use a soft tissue to clean the reflectors.

the surface.
D.
Strobe Tube Replacement.
WARNING
High voltages are present inside the
lightbar. Wait at least ten (10) minutes,
after shutting off power, before servicing
this unit. Failure to do so may result in
property damage, serious injury, or
death to you or others.
Disconnect ALL power to the lightbar before
any maintenance is performed.
As strobe lights are used, flash tubes begin
to darken, causing the light output to decrease. Also,
as flash tubes age, they may have a tendency to
misfire (not fire periodically).
After extended operation, occasionally
check for flash tube degradation. Should the tube
misfire, have a noticeable decrease in light output,
glow continuously, or darken excessively, it should be
replaced.
NOTE
Not replacing a strobe tube when any of the
above conditions exist could cause a break-
down of other power supply components.
For Primary Linear Strobe Tube replace-
ment, see figure 4 and proceed as follows:
1.
Refer to table 2 for the correct strobe
tube part number.
2.
Remove and retain the screw which
secures the defective strobe head assembly to the
dome. Remove and retain the two screws which
secure the lens to the strobe head assembly.
3.
Insert a small flat head screwdriver in
the slot on the back of the reflector. Note the strobe
tube’s orientation and gently push forward to release
the defective strobe tube.
