So on my 04 Heritage I noticed one of the front running lights was out. Turn signal still worked. Stopped at the local store and bought what I thought would work, 1157. Put it in, and it is much brighter than the old bulb and does not blink. Hmmm....swapped it with the other side, known good bulb, still no go, but the old bulb worked perfectly. I guess its off to the dealer just to get a darn bulb.
