i bought i set of those for my ef, before i installed them i put a nice seal of clear rtv silicone around the plastic and the clear cover, enough so no condensation gets in, but not enough to be noticed when looking at them. i have no problem with light output, currently running silverstars and the light extends 100's of feet in front of the car illuminating everything. some people just put these down because ricers killed them off but i like the look of them over the stock lights, even ones retrofitted. i say if you want them, then get them. it's your car anyways.
