Yes they would be brighter, could you not take them back and get your money back or have you had them a while?.........................if you have, then just keep them because you can use them as a spare in your XT, I keep a full set in mine of all the bulbs and mini fuses as I was once told that if your pulled by the police with a rear light out and you carry a set with you, then they can't have you for it if you said they were working when you started out. When you get these philips bulbs they often come with a set of blue side light bulbs don't put these is your lamps as they're for show displays, the law says that you should have white lights at the front of your vehicle, Just because they have EU safety mark on them doesn't mean you can fit them, it's just to say they meet the EU standards. Hope this helps you. :thumbs:Tess said:Hi Umbongo
