Almost alway in DC wiring with the exception of marine applications, red is hot and black is ground. I would like to expand this thread a little to the newer style fog lamps:
I bought on E-Bay a replacement set of fog lights for my 2017 Energi. They didn't work. The vendor is naturally reluctant to replace them and if there is something I'm missing I don't want to bother them. However, it's not rocket science to plug these in and tell if they are working or not. So I'm wondering how I can test these further. I tried:
Installing them - Nada
Testing continuity - Nada
So I thought I'd apply voltage to the light, but am unsure as to which prong is which.
Can someone help me with this?
The newer version (2018) - Can these be repaired or do we have to buy the whole Assembly?
Which prong is positive.
We are not pikers and have a serious shop.
