DIY headlights are a good idea if you have any kind of skills at all...they really aren't that hard to do...if you do it right they'll come out great...i had a set of aftermarket black housing headlights on my 6th gen accord, but somebody hit me in a parking lot and tore one of them up. i had the stock set still in my house, so i blacked them out...they came out great...they look better, and fit 100% better than those others...so it's not the DIY, it's the person who does the work that dictates the quality of the job. my DIY's have never leaked, the ones i bought did tho.
