yeah they are great bulbs, as you know youve got to be carefull when putting them in not to touch the glass, oils from your fingers are hard on them any will shorten the life of them , yes read the warning right on the side of them , ive heard many people say the same thing, they are very powerfull!,run them for about 30min and feel the wiring behind the plug, ive got a friend that had his melt the harness, when he contacted the company they said they couldnt help him,that sucks,but they look great once installed!, but just gotta check to see if they are hot.
