Star Headlight & Lantern TD93DLXT - Manual (Page 11)

Replacement Parts
These traffic directors all use state-of-the-art light Emitting Diode (LED)
technology. These lightsticks are comprised of eight segments of Ultra-Bright
LEDs that are operated in a multiplexed mode to efficiently produce light
output with lifetimes up to 100,000 hours. Under normal circumstances, you
will not need to replace any lights in these lightsticks.
TD92 and TD93
If any of the LED's in your lightstick do fail, please contact the factory for arrangements to
have them repaired.
TD93DLXT and TD93DLXT24
The TD93DLXT series are designed such that if there is a failure in one of the arrays, the
array can easily be replaced without removing the lightstick from the vehicle. The
replacement head is a part #TD93DLXTRH-* or TD93DLXT24RH-* (*=color).
TD77-2 Series Controllers
The TD77-2 controller, used with all of the traffic directors, contains two ATO "blade-type"
fuses located in the back of the controller. The fuses are accessible from the rear of the
controller. The 20 amp fuse controls power to the bar light assembly, while the 5 amp fuse
powers the controller. If the 20-amp fuse blows the controller will continue to function
normally, however, the roof lamps will not. It is important to note that under normal
circumstances the only reason a fuse will blow is because there is a fault in the system.
If
a fuse blows repeatedly it is a signal that something is wrong. Do not replace a blown
fuse with anything other than the same amperage rating as marked on the rear panel of
the controller; doing so may damage the unit, or worse yet start a fire. Likely causes of
blown fuses are improper wiring, harness damage, and/or improper bulb type.
