C3 rear lights

[Brads]

I’ve currently got a C3 which I’m trying to sort out the rear lights.
It currently has the outer lights that have side lights with brake lights combined which is okay, where my issue is, is that the inner lights only have a turn signal utilising the reverse lenses with amber bulbs.
I’m trying to find a way to have turn signals “and” reverse lights??
The only way I can see this being possible is to have Red outer turn signals and inner white reversing light?
Has anyone had any experience as I’m trying to find the build holders and bulbs to make it work.
Pictures are of the inner lights

This is a job on my to do list!

You can buy switch back led bulbs which have white and amber lights in the same unit. The problem with led indicators though is that the resistance will be too low for them to flash at the correct rate, so you will need to wire in some resistors.
