Over the past year of riding I've experienced something with my turn signals two times that has me puzzled...both times when the front turn signals needed to be replaced: After putting new 1157 bulbs in the signals the blink rate was faster in the signal, which would lead you to believe there was still a problem. However, the light was working fine, so I left it in...then after a week or two of riding it returned to the normal blink rate. Anyone else experience this, and if so, do you have any idea what causes it?
