Maaaaan.... I see red halos, green strobes, even RGB unicorn sparkles... Cops here cant do jack.
I want GT yellow headlights, I know for a fact, I'd get thrown in jail on the spot 5 minutes after installing them. But some people can get away with driving with 2 LED light bars on, cops see only what they want to see.
Sorry, I'm in a bit of a rant. I've wondered about changing the color temperature of the DRL's myself.
That being said, if you are really motivated you can probably replace the individual LEDs with different colors (actually now that I think about it, it might be possible to hook one of these strips with LEDs that have RGB LEDs so you can choose almost any color by a hardwired remote or app - most of these run on 12V already so not much would need to change and there are some that are dedicated to be installed outdoors).
These Ford Focus DRL Boards will take your vehicle to the next level! Featuring full color functionality like our RGB, HOWEVER, this kit also offers a solid white output in exactly like OEM along with switchback functionality for your turn signals!
They're LED, and it's technically non-serviceable. Just like the rear running lights, they're built into the housing. If you want customized colours, you'd have to replace the LEDs by baking open the assembly. Be careful, the headlight assemblies aren't cheap.
The DRL LED controller is housed inside the headlight assembly, the car only sends a signal to the headlights telling the headlights to have DRL fully on, dim, or off. Because of this, different headlight assemblies made from different batches will have binning issues, i.e. the DRL colours and brightness are made to within a certain tolerance, and that tolerance does not appear to be very tight. What this means is if you have two headlights from different batches, the DRLs may appear noticeably different.
