I washed the car this morning, and then it rained this afternoon, but I guess that's good for product testing. So far so good, no leaks. I did this mod on my OEM Red/pink lights while the red/clears were still on the car, but then the red clears started to leak a few weeks ago, so that's why the modded pinks went back on.I used 168's which are the same as on the current tail lamp. After I fix the leaky lights, I am going to do this mod to them as well, so I will take plenty of pictures for a How-To.
