If you should be in need of tail light bulbs for your BMW or MINI, be sure that you are buying the correct bulbs that will not interfere with your check control system. You will want the German/European bulbs that have a stainless steel base, (socket base). These can be purchased at an experienced BMW independent shop or your local dealer. Do not go to the closest big box parts place and pick up the American brass socketed bulbs. You will probably get the same warning indicator light because the resistance value is not compatible.Also, worth noting; the xenon headlight bulbs are excellent at giving the BMW driver outstanding visibility. They should give you many, many years of reliable performance, but they are expensive when it comes time to replace. Once again, go to an experienced BMW independent or dealership for these replacements.First of all, you have to be sure that you actually need bulbs, and that the problem is not something else. That is another good reason why it is always best to trust your BMW or MINI to someone who has been working ONLY with BMW for decades. They will be the ones who have serviced and repaired thousands of BMW’s, not just a couple a week.
