I’m going to install an OEM fog light kit on my 2014 Eco pretty soon, but there’s one thing I’m a little unclear on. I’ve read on this forum somewhere that you can run the fog lights and park lights instead of the headlight DRLs. However, I’m in Canada where every car must have DRLs on whenever the car isn’t in park, or in my case because my car is standard, whenever the handbrake is down. What I’m wondering is if I can drive around with only my park lights and fog lights on, so that I can save the lifespan of my headlights and because I like the look. Any input would be greatly appreciated!

Thanks!

I am going to answer based on my 2014 LT. The headlights are used as the DRL's by modulating the voltage output out to them. I suppose it is possible to use a hall effect sensor - I think these work with DC - to sense output to the headlamps. You would need to be able to tell when the full voltage vs the modulated voltage is being supplied. Once those voltages are compared, sensing the lower output, you could use a NO set of contacts on a relay to close in the fogs and a set of NC set of contacts to open the headlamps. This still leaves the issue of switching back. It is a matter of finding the right type of sensors and then getting the logic to work. Good Luck.

I actually just received a custom wiring harness from Gen5DIY last week. I installed it yesterday and it does exactly what you're wanting, diverts the DRL voltage from the headlights to the fog lights. Here is a link to the parking light version, I specified during my order I want the fog light version: 2011-2014 Cruze DRL Relocate Harness-Parking Lights

However, I am having one issue with it; I am unable to turn the fog lights on at night without having the 15A Fog Lamp fuse blow. I'm not sure on the specs of the harness but I'll be contacting them tomorrow to troubleshoot the issue. Other than that, it works great. My future plan is to install HIDs and the pulsating DRL voltage would kill an HID system. This harness is a simple DIY project to work around that issue. In general, I like the look of it as you do. It sets the car apart from the other Cruze's on the road.

@Live Trash. What's in that harness that converts the PWM signal in DRL mode to a non PWM signal? I'm thinking it's a series of relays with a capacitor. Can you confirm this?
