Question about Jeep CJ7
Good news is that you don't have any control modules etc to deal with. Check for power using a test light. Start by checking the actual bulb sockets and all fuses. Make sure the socket grounds are good
(if there is power at the center contact for a bulb but the bulb does not come on the ground is bad).
Also check the light switch itself to make sure power is coming out to the wire for those lights.
An easy way to find which wire from the switch is for those lights is to connect battery power to the hot wire of any of the running light bulbs and then check the connector at the switch to see what becomes hot (has power) that did not before you did that. No power there tells you that there is a disconnect somewhere in the harness. Trace the wire using the test light as a probe to see where the power stops. If that same wire isn't hot when connected to the switch with the lights on, likely the switch itself is bad. (test done with "test" power not connected to the harness)
Never use this test method in any newer vehicle or you can damage control modules.
Any questions about what you find, just ask.
