Hello, at my CR-V Executive a xenon pear has said goodbye, it only shines reddish. I would like to change it, since someone has a guide for. Have the air channel already broken down, but don’t see exactly where the pear is attached. For a tip I would be grateful? Does someone know which bulb I need D1S, D2S? Should you change both pears immediately? Thanks for your help? Greeting Thomas
