I had a buddy who bought the el cheapo HID kit on eBay (~$40) and he no longer has working instrument cluster displays. One screen in the cluster 50% the right side and the lower screen is dead completely. It happened within 10 seconds of turning on the HIDs for the first time. If your going to do it then get the higher quality ones and make sure to get the resistors or like everyone else said get it coded out.
