The front one is going to be the biggest pain. The Side neons and rear are up high enough even on a significantly lowered car that they wont get hit. The front one sits so low because there is very little space to mount it. It will still be exposed to the elements and road debris. As far as them getting dirty, they do but it doesnt really affect the lighting as far as i remember :thinking:
Dont get OPTX what ever you do. Those sucked tremendously
