Just fitted these to my T6 mine has the H4 bulbs, they are quite a bit brighter as you will see in the following pics, and just to advise when changing the drivers side remove the air filter box to save time and frustration, took only couple of minutes to take airbox off and then it's so easy to replace the bulb. See pics below of bulbs fitted before and after, big difference and will keep you posted on how long they last.
