I ordered these when the dealership quoted me almost $500 to replace one headlight bulb. I had to pay the dealership $139 to replace both lights as it is not possible to get to them without moving a lot of parts in my Jeep Grand Cherokee. They’ve only been installed for a couple of months now so I can’t comment on the longevity, but I cannot tell any difference in the brightness or function of these bulbs when compared to the originals which were in place when I bought the vehicle.
