As the title suggests can anyone confirm the exact size of the torx screw size. The set I have is either too big or too small. I think it was the TS25 was too small and TS27 was too big. can you get a TS26? if so I cant seem to find this size on the web when searching. cheers in advance. ps All I want to do is change my Xenon bulbs to 6500k!
