3157 or 3457
Does anyone know the differance between the 2. I have a set of 3157ST from my Cirrus and they look identical to the 3457ST right down to the filaments. Anybody see a reason not to use them? I plugged them in and they work for all operations but before I use for extended use, just wanted ot see if there could be a problem. Figured i could save $20 by using the 3157's.
