I can push it back and it stays, but the
problem is that the wiring from the lamp that meets housing is broken, so it would need to be resoldered.
Sent an email to HorizonLeds, and they said I could send this one back so they can process a replacement, so Happy Days!
Now I have bought previously some crappy Leds that I did managed to replace on the driver side, but never in the passenger one, in the end gave up and sent back as there was no output and the color didnt match.
Now after checking you guys pics with these Leds, I decided to give another try, so bought it but by mistake only got one, so ordered the second yesterday and this morning attempted the passenger side first as it was the one I couldnt replace last time.
I did just as you described, but this time used my right hand to pull the washer a bit, just enough to be able to pull down the connector with my left hadn, and man this time it worked. The worst part was yet to come, as you said it was hard to plug the connector back onto the new fog light, and in one or two attempts, it broke...
I am pretty sure I wasnt being brute, but well I am waiting now for the second one to arrive any day now and ill give it a go, I havent even bothered to plug the OEM Halogen one.
