Mine is a 95 Cadillac Eldorado has 30,000 miles on it. Clean! one question, my brake lights work fine. But the other day I got stopped by a dumb *smurf* cop who said they were out, keep in mind it was bright as day outside at this time. So I was like ok. When I went into my garage, being it's dark in my garage, my automatic lights turned. I got out of my car and what do you know! My brake lights are on! And when pressed on the brake pedal they get brighter as well. When I backed out of the garage in the daylight of course the automatic lights turned off, but this time I pressed to button for my lights to come on and STILL..my brake lights work! So the reason for me writing this is to ask if anyone knows that the feature for the tail light brake lights to not be on during the daylight and only the brake light in the back window to be on during daylight is a feature thats normal? Like is it a feature that Cadillac made to save energy?
