FYI. You can use LED if you like, but don't make the blanket statement they are "better. For me in this location, they have not proven reliable over the long haul. Future improvements will change this I suspect. For now, I will stick with proper factory bulb. These are easy to service and repair but are a dealer only item and may not be available at all new depending on when you are watching this video.
