If you want cheap…get 55w 6000k HID’s from DDM. They will look like 5000k. Nice mix of white with a small hint of blue. The best kelvin is 4300k because that is most similar to our sun. The further you go from that (up or down) the less lumens you get thus meaning less usable light. I’d stick to 4300-6000 for headlights and 3000-6000 for fog lights.
I’m switching out my DDM stuff for some real pricey Morimoto stuff from TheRetrofitSource.com.
Morimoto, in testing, has shown to have 20% more light output than DDM or comparable ‘cheap’ kits. I’m going with 50w 6000k (top) and 3000k (35w) bottom again.
I’m not sure about the quality of the headlight…but it’s not recommended to use 50/55w anywhere but headlights. They are usually too powerful for fog lights. And be aware that DDM tends to drop ship, so it may be a few weeks till you get your kit.
