If it required a small amount of modification, that'd be okay. Of course, you don't want to pull the bulbs too far back or it will change their effectiveness.

Maybe there is some readily available bulb socket that could replace all of the plastic ones. Heck, make it so it improves the performance of the whole system and people would be even more enthusiastic about it. You could include a way to make it so it uses the fog lights for brakes right out of the box and that alone would get you a lot.

When I contemplated soldering, I thought about attaching to the plastic socket part. The metal contacts are reachable from behind.
