Well to give you all an idea on how bad the lights were on my 95 Bonneville, it still had both original low beams, high beams and one fog light bulb
I can say this for sure at least from when I purchased it in 1999, but I'm willing to bet they are from the factory.
When I bought the car I never used the fog lights much, they really didn't seem to help much at all anyways. I didn't pay any attention to it but I had started to use them all the time. Well I decided to give the Silverstars a try and wow what a difference it made. I was going to just do the highbeam mode with the low beams but this was easer to do lol. I did replace the high beams with standard bulbs but I am going to do the Silverstars with them as well after seeing how nice these things are.
