Question about GMC Yukon XL
Check fuse for tail and parking lights
Could be a bad dimming rheostat
Could be a bad headlight switch
theres a switch at the brake lever(bad) or the bulb is out
Look at the fuse panel and if you have a manual that will tellyou the tail light fuse then check it. If not then pull them one at a time and replace any you find that are bad. If none turn out bad then there is a relay in some models after the fuse. It should be mounted under the steering wheel dash area.
