The front signal lights are actually legal if they are white. They ARE NOT legal if you put them in the back, and it's sooo much easier to get pulled over for those.

Blue is always illegal...anywhere. As for hyperwhite...they're still not white to some cops. Especially when they turn off and they have that blue filtering lens.

front bulbs are usually 1157's and rear signals 1156 but if they come on with the parking lights and then have the function to blink or come on with the brakelights then those bulbs are 1157's.
