Just to share what i found, when those bulbs go out it is often an indicator of a cracked light casing. Water gets in there and wrecks the bulbs. I replaced mine and it went for about two years before burning out again. Do not buy the aftermarket light housings off of ebay, they suck. They look like shit after a few months and dont fit on the stock wiring harness. If anyone took off those running boards and has teh light housings and is willing to sell them for a good price, i would be more then happy to take them up cough cough.
