Replacing porch light, but no ground wire from house


When I removed the old porch light, I found there was no ground wire from the house and the ground from the light fixture was just loose. There are just a white wire and a red wire coming from the house. The new fixture has a black wire, a white wire and a ground.
How do I proceed?
Thanks.

You have no ground available so leave it as the old fixture was unless you want to pull a ground from the house panel.

If it's an older house and the light and wiring were put into place before grounding was required by code, you can just replace it without ground by hooking up the white wire to white and red to black. If ground was required by code at the time and it was put in incorrectly, then it should be corrected by running a wire with ground to it.

Yes, it's a concrete block house almost 50 years old..
Thanks to both posters for the info.

You might want to consider installing a fixture that doesn't have any exposed metal parts. It will be marginally safer.
Obvioiusly, the best approach is to replace the cable with a grounding cable. Alternatively, you can install a GFCI on the circuit. This will provide protection against electrocution that's superior to that provided by a "proper" ground connection.

It is quite possible that the ground was, and hopefully is, provided by a conduit to the box. I would check that and assuming the box is grounded make sure the fixture is also properly grounded to the box.

If you have a white and red conductor from the house, it's not in a cable, therefore it must be in a conduit of some sort. If it's fifty years old, most likely that conduit will be metallic, and provides the grounding for the circuit. Connect the black to red, white to white and ground to the box or fixture bar which is screwed to the box.

If the electrical box is metal and the wiring comes into the box with armored cable (BX) or metal conduit, the grounding is provided by the metal jacket or the pipe. If this is the case you would ground the wire from the fixture to the metal box using a separate screw or a grounding clip.
