If you will be synchronizing two or more units together, 

leave the white wires disconnected until 

programming for each has been completed

.  Connect the white wires from the units together 

ONLY AFTER PROGRAMMING

 them all for the same Pattern Type (Phase MAY differ). 

Wiring 

When wiring your lights, it is recommended that you take the following 
precautions to reduce any Electromagnetic Interference (EMI). 

 

 

Keep LED modules and any radios as far away from each other as possible. 

 

 

Separate the radio wires and the LED wires. 

 

 

Any excess wires should be cut short. 

 

 

The Ground wire, Power wire, and Synchronization wire should be bound tightly 
together as they run from light to light, through your switchbox, and to the battery. 

 

 

Do not ground each unit independently to the chassis.  Run the ground for each unit  
in a “bus” like structure, to the negative terminal on the battery. 

 

Note:

 The total wire length between the two farthest units should be no more than 40 feet.

Programming 

After the lights have been installed, and 

prior to connecting all of your wires

, there are 

several options you will need to decide upon and program.   

 

The options 

MUST BE PROGRAMMED

 

IN THE PROPER ORDER

 before use: 

 

A. 

Single/Split: 

Do you want your lights to operate in Single Mode or Split Mode? 

 
 

B. 

Opposite Light Function

 - When your lights are activated in Warning Mode and you 

turn on your Turn Signal (blinker), what do you want the opposite light to do: 

 

Continue flashing in the pre-programmed warning pattern 

 

Turn off  

 

Become steady burn 

 
 

C. 

Warning Light Pattern: 

What warning pattern do you want displayed when you 

power up your DLHT lights?
