I probably wouldn't do the LEDs in my B13, but I did them in my 2016 Mazda3. I wanted to get the factory LEDs for headlights when I was trying to buy the new Mazda3 (lots of night driving and lots of deer around), but with a stick I could only find one car in all of CA available new with that package, and it was overpriced. So I got the lower trim and decided to get LED bulbs for it. The factory housing has the cutoff line on it, so I wasn't too worried about glare/blinding drivers. I got this one:

Below is a shot with one side with the LEDs installed and the other the factory bulb. In the center of the primary pattern, they are probably equal, the the spread/coverage of the LED is way better. I have yet in 6 months have anyone flash me thinking I had my brights on. I'm quite happy with these and do it again - assuming whatever car I was doing it on has the cutoff line.
