Black interior, black hard top liner, very dark in the JT; sometimes the dome light just isn't bright enough for me. My solution to adding manual-switchable auxiliary interior lights controlled by the OEM dome light circuit.
Village Idiot Solution
Flashlight, current method in use.
More advance but an easy solution
Directly tap into the dome lights circuit to power auxiliary low powered LED lights to supplement the dome light. See: https://www.jlwranglerforums.com/fo...rior-dome-lighting-to-rigid-industries.37559/
Then my more difficult approach (the flashlight was so easy).
My JT came with LED footwell lighting (may not be available on all JT trims). There is a 3-wire plug to the small LED lights under the drives and passengers dash, The black wire is a common ground, from the headlight control, the left wheel on the headlight switch controls the footwell lights (white wire with green stripe), the right wheel controls the dash and dome lights (yellow wire with violet stipe). The yellow wire with violet stipe (smallest diameter of all three wires) is the wire to be used to trigger the dome light relay. I will be using a relay to control my auxiliary interior light(s) because the light(s) I use may over-tax the CAN bus dome light circuit maximum wattage.
When the dome light turns off they slowly fade to off (12 volts fades slowly down to 0 volts). So if a relay coil is hooked directly to the dome light circuit, the relay will buzz (the contacts opening and closing rapidly) while the dome light is powering down. To stop the contact buzzing, I placed a 1000 μF 25 Volt polarized Electrolytic capacitor parallel across the relay coil (this keeps the relay energized just long enough until the dome light circuit finally drops to 0 volts). Also placed a diode in series between the dome light circuit tap and the relay coil.
I now have the hard part done; all the wiring done and the circuit tested, a 2-wire terminates close by the dome light on the sound bar that will power the auxiliary dome light(s). Now I'm determining what type of light(s) to use and where/how to mount.
