Now I have angel eyes + fog lights as DRL. And I notice that I can change voltage for low and high beam and increase them to 13.8v. I think I can also change fog lights as well.
My question is: is 13.8v too much that will shorten life of the bulb? I think the factory output is 13v.

If you have LED bulbs they often come with their own drivers and control voltage independently so you won't see any difference. Just for your info.
