White are very difficult to find, I've never seen them in an actual 1157 style bulb, only as a panel with an 1157 style plug in and as single led panel lights. Obviously, red will be no good up front, as that would be illegal, best improvise I can suggest would be to use the amber illumination LEDs. You may have to special order them if you're soucing them locally, APC does make them. My local speed shop had a hard time getting them as the supplier kept sending red ones. I doknow that Harmons has them in amber 1157s, in boht 9 and 21 LED bulbs. I recently swapped my 9 LED APCs for the 21s, not a direct fit, some alteration was needed to make it fit right due to the much larger diameter of the lighting part. They are considerably brighter, though.
BTW, when off, they do not show through the clear lenses, so it still maintains a stock look.
