seriously save your money on that TYPE_ RRRRRRRR bullshit,
do not buy HALOGEN BULBS.
buy this set of HID in 55watt in a 5000k or 6000k seriously do not go over 6000k, i have 6000k on a 55watt kit and for me it is too much color. the higher the K the lower the brightness of the output and the spread and intensity. stock bimmers and mercs run around 4100l-4300k.
55watt kits are brighter but honestly only run like 45-48 watts, the tend to wash color a little so a 6000k can look like a 5000k. on regular kits do not go 6000k too much color and reduce your light.
i used the regular kit on my car for them which was a slight bit cheaper and i have no issue with light out warning or anything like other on the board. I tapped right into the h7 plug without any splicing at all.
pick up the 55 watt 5000k-6000k
pick up the 35 watt 4000k-5000k
