OK I will try them first. I had problems with the first set I bought some 5 years ago and they were replaced under warranty as some of the LEDs failed but they were also showing a dash board warning light at the time. I actually bought them from a LOC member trading on Ebay (Scorcher), don't know if he is still a LOC member. So these lights are new but I have actually had them for 4 years and not used them so the questions is I don't know if they do have the resistors built in. Once fitted I will let you all know how they perform.
