LED front turn signals

[ZKrazy]

so i was planning on changing out the front bulbs to clear but through research found out that its pretty impossible to find 3757 anywhere in clear. i also read that the 3157 can be used with little modification. is there anyone here that has used 3157 led bulbs for the front? if so, did you also have to install a load resistor to prevent the lights from blinking fast? if anyone has pics, that would be great as well.
