We recently purchased a 2016 Yukon XL SLT. It bothers me that the high beams, low beams and fog lights are not as bright as the putter lights(daytime running light I guess). Can anyone tell me if you have replaced these lights and with what? Did you have to cut a hole in the cover of the existing light for the new bulb to fit? I contacted a local dealership and they gave me an estimate of $660 to convert the lights for me. Any and all advice is appreciated.
