I have been looking into switching out the stock halogen bulbs in my iM for LEDs but I have a couple questions. First, I don't know what color of bulbs to get, I want them to match the DRLs as close as possible so should I go 5000k, 6000k, 7000k or something else? Second, I have heard some people complain about the noise coming from the fans on the LED bulbs, is that a sign of a poor quality bulb or is it a legitimate problem for all LED conversion kits? Lastly, what is Canbus? Some people are saying you need to install one with your LEDs, is it a part, or a brand, is it necessary? Any and all responses will be very helpful, thank you in advance
