Kia K4 Flow Series DRL Boards (2025+)
What are DRL boards? Keep your headlights. Add multicolor daytime running lights.
DRL stands for daytime running light. A DRL board is the small LED circuit board that lights up your headlight’s daytime running light strip.
- What you keep
- With a factory-fit kit, you keep your original headlight housings, lenses and optics. The new LEDs shine through the factory DRL light guides, so the light keeps its original shape.
- What you upgrade
- A board kit changes the lighting inside the headlights you already own. You get multicolor DRLs for less than buying complete prebuilt headlights. Color modes depend on the kit.
- What installation looks like
- Some kits swap through an access point. Others require opening and resealing the housing. Butyl-sealed headlights are often easier to open than they look. Hard-sealed housings can take more work. Check this listing for the method that fits your headlights.
