Road lamps don’t have a ground

My car was missing the road lamp harness from the firewall to the lamps and the switch.  Picked those up but noticed the road lamps have 2 bullet nose connectors.  Looking at the manual and the road lamps vendors are selling each lamp should have a ground eyelit connector.

  Has anyone seen them like this before?  I did a quick 12v check with and there seems to be no polarity.

I don't think it matters which one is the ground.

The mustang road lamps are near identical to the cuda road lamps and are sold as a cheap alternative..The quick and easy ID is the mustang units have rivets around the housing to hold the inner braces...The harness you have is for the mustang..As stated, pic your end and install the ring terminal...At one time you could buy the cuda  harness for the road lamps ...Blue wire would have the bullit connector and black would have the ring terminal...

If you were to switch to a LED light in there Polarity will matter FYI

Actually, if the filament is wound clockwise, the positive voltage has to go in on the left, grounded on the right...

If it's wound counter-clockwise, then the current flow should be opposite of that...

Actually, in all circuits, the current really does flow opposite the voltage.... from negative to positive!

Maybe they are that way because they drive on the left side of the road.  :notsure:
