As requested, the LED bulbs I bought are here – https://www.ebay.co.uk/itm/Xenon-White-Car-Bulbs-C5W-12-SMD-Error-Free-Lights-Festoon-LED-Interior-31-42mm/202665748695
The 42mm long option – I personally bought 4 just because the price works out better but chances are I’ll never use them all so it might be a saving not worth making.
