OK we have cover this before, I just did my truck to day, and it only took ten min. I took a few photo of the lights before and after and posted on my webpgae, and you got to check this out it's cool!!! scroll down to "Hey My Front Park Lamps Won't Stay On!" and then watch that photo change, it will do so 7 times.
