Cheap Chinese Replica Parts

Recently, I had purchased a turn signal switch from Victoria British Upon recieving the switch that looked like a pretty good, copy of the original (also labeled "Made in China") I was happy to have a the new part it was just new and in a 35 year old car anything new helps! After installing the switch and trying to use my brights (headlamps) the switch simply snapped in half! Yikes! Okay so I called Victoria British and they were nice enough to refund or exchange the part plus shipping. They didn't even want the "old part" back. I did not want another one. My plan was to purchased the switch from Moss Motors I did and recieved it,(it was made in Taiwan) installed it and it worked for about two weeks. The turn signals stopped working so I bought a new flasher, that didn't work so after some research, I found out that the Harzard switch could be the cause and it was. All the contacts inside the switch were dirty. The switch can be cleaned if it is disassembled. Which I did then everything worked. About two months later my both my headlights stopped working. I was thinking it could be the old headlight switch. I disassembled it and cleaned it and it worked for about another month.
Then my both my headlights stopped working again, I knew I had good grounds because the passing brights would illuminate. I suspected I needed a new headlight switch. I bought one from Victoria British received it, installed it and to no avail: no headights still.
Which brings me back from the start. I found my original turn signal switch just plugged it in and voila! my headlights worked!
I'm telling you these replicas from China or Taiwan are lousy repros, when you think that my original switch is 35 years old!
I'm going to call Moss Motors and let them know how crappy these reproduction parts are from Taiwan and China!
