Driving lights

[Ripp6957]

I have a 2020 Edge titanium and want to add better driving lights. I bought two 150 watt lights and was wondering if I could just use the existing wiring for the stock fog lights. I would just disconnect the existing lights and attach the new lights there. That way they would turn off with brights on. Sound feasible, or would the new lights be too much draw on existing wiring, fuse and relay?

Thanks in advance.

I think you will have to run new wires.  The lights will draw at least 12 amps.  The wires for the fog lights were not designed for this high of a load.

The fog lights use 20 gauge wire. They are just small LED lights. If you try to draw more power, the BCM will trip.

The BCM utilizes an Field Effect Transistor (FET) protective circuit strategy for many of its outputs, for example, lamp output circuits. Output loads (current level) are monitored for excessive current (typically short circuits) and are shut down (turns off the voltage or ground provided by the module) when a fault event is detected.

 

If the lights use 300 watts at 12V DC, it will draw about: 25 amps.
Current = Power / Voltage. 300 W / 12 V = 25 amps (often more at startup).

Instead, you should run new wires, fuses, and relays.
