you can pick up some led load resistors at an auto shop.

i've been meaning to pick some up for my versa, since i changed the front turn signals/ daytime lights to leds. they've been on hyper flash since, they really don't bother me but i feel like they'll burn out twice as fast.
i know there's a fuse out there for replacing the resistors because they get really hot. but i forgot where they were being sold at.
