Do You Need a Logic Module?


If you are replacing an existing third brake light, the wiring harness already includes the proper wiring. However, if you are installing a third brake light where one did not exist before, you may need a logic module.

If your vehicle has separate red brake lights and amber turn signals, you will not need the logic module. Simply connect the new brake light to your brake light circuit.

If your vehicle uses the same red lights to indicate braking and turning, and your vehicle was not previously equiped with a third brake light, you will need a logic module for the 3rd brake light to function properly.

The logic module connects to the left and the right brake/turn signal circuit. When the brakes are applied, a signal is generated from the logic module which is connected to the third brake light.

The part number for the third brake light logic module is 18-6
