So ive wired up a rear interior light. I wanted it to work as a courtesy light so I tapped into the front light, took a feed off each cable on the front light and wired up to the rear one.
The rear light works but only off all the doors are shut and the front courtesy illumination is gone.
If the rear light is On and i open a door it switches off the front courtesy light comes on.
Ive done something wrong but not sure what?
Talk me through how you wired your second interior light... have you used another TD5 interior light fitting with the 3 position switch?
You can fit a second light, that will be controlled by the main light, in that it will just mimic whatever the front one is doing, provided you splice into the bulb feed pins only in your original light,
and you bypass the switch in the second light, in essence wiring two lamps in parallel assuming you are using cob led blocks etc
Any other way it gets very upset and you have lighting bingo as you are experiencing.
It becomes a PIA if you want to work it independently from front. (cos its all controlled by the ECU/Alarm system)
So for me I need to control it independently as I have a van, (load area) so straight up perm live feed and job done.
However as you have a posh DC front light mimic/repeater is probably best.
Am i making any sense here?
