There are several ways to do it. On my '09 I tried to use amber 18-LED bulbs to replace my parking/turn signal bulbs and then use them as DRLs instead of the low beams. The individual LEDs started to burn out, flickering as they went. Since they also weren't as bright as my incandescent bulbs I ended putting them back in and just used them as my DRLs.
I applied that learned lesson to my '11 and modified my car to have the turn signal filaments illuminate as DRLs instead of the low beams. That gives me a bright amber light in the daytime instead of a white light, which at least one Federal study determined was more obvious. But so long as there's a light that's safer than driving dark.
Did you install your 5K switchbacks in place of the parking/turn signal bulbs, or did you add them to the housing by modifiying it? It'd be neat to see some pics, too, please!
