I had a small issue. The metal cap holding the yellow tinted glass tube in place fell off in my fog light housing. The tube also fell off before I could fix it and I had 1 white fog light!\n\nI have since fixed the issue with some loctite on both posts for the caps, but thought you'd like to know. I've attached a pic of the cap lying in the housing. \n\nOverall, they are great. Love the light output. I've also attached a pic of that from a recent snow storm we had.
