Interior lighting not working

Recently I have installed a new radio in the car, I used a vacant slot to provide power and within the next week I realised that my interior lights no longer work from opening door and turning them on manually, unsure if it's coincidence or related.

I have checked the bulbs and they seem ok, I have used a volt meter and all of the fuses seem to work. I used the voltmeter into the bulb location with it switched on and didn't get a reading.

Am I missing something and does someone know the right fuse for interior light? Also part of my light switch panel illumination by the driver door no longer works.
