Where to get quality light sockets

I bought some salvage sockets from a member. After I wired them up, I enveloped the backside of entire front side marker light in a glob of duct-seal hoping to prevent the new lights & sockets from corroding. The pot metal 68 light gets spray from the front tire.
As a side note, I also got tail/brake light sockets and installed in my reverse location . I used amber/white switchback LEDs behind the reverse lens for turn/reverse and bypassed the brake light circuit from the flasher, so now I have both brake lights operating when I also have turn signals on.
