I bought the smoked clear Cobra headlight kit w/corners from Blue Oval Industries.
The install was pretty easy, the quality looked very good, and they look very nice on the car. I did nothing to the lights prior to installtion......no sealing or anything.
After a year now, I have no leaks and the lights look like they just came out of the box yesterday. After loads of road trips, gas station car washes, detailing, washing it myself, and so on, there has been no leaks or defects at all.
Most people comment on how nice they look, but don't know that they aren't factory stock. The stangers that see them comment on how nice it cleans up the front. The stock headlights on most 94/95 stangs are pretty bad looking. I actually though the Blue Oval lights were a little better in quality than stock.
Thumbs up from me!
