Basically got 8 years and 113,000 miles out of the OEM bulbs, I am quite impressed they lasted that long. Replacing them only took about 15 minutes. However since it is easy and cheap I am contemplating also swapping out the brake and tail light bulbs while the weather is nice, don't want to do it in the winter if I don't have too. What do guys think? have any of you had them actually burn out yet? I have no interest in upgrading to LED's, old school is fine for me.
