One might be brighter than the other due to the wiring resistance. But yes, they both fit. You might have issues, you might not. But use 3057.


It appears the 3157 is listed as a "long life", and the 3057 is the standard bulb, depending on how much more they want for the 3157 and how difficult they are to change will make the decision for you.
