Hello the List, I am about to put 100/80w replacement lamps in my 200tq20v. I have had euros in other cars, and have made up a harness. So I know how to do that. But I am now being told by people who claim to have sold lots of these bulbs that it is not necessary to build a harness. They say they have never had a meltdown. Any opinions as to who's right? Thanks, Roger
