I seem to get asked about competition numbers a lot, and how to get hold of them. The normal answer is 'ask a sign shop for cut vinyl', but if you want to just buy online and have them delivered, here's some useful links:
Section J of the MSUK yearbook, which describes the specification of the number backgrounds: https://www.motorsportuk.org/wp-content/uploads/2021/12/146-165-Vehicles-J-2.pdf
Our regs override this in some areas:
- the number backgrounds need to be reflective white vinyl for the 24hr.
- additional numbers are required to be displayed in the left side rear quarter window. Ideally these should be fluorescent yellow/orange
- Decals for above and below the number background - currently there is only one, which is the "2cvparts.com" sticker, which needs to be above the number background. These are available from Roy at ECAS.

White reflective vinyl for door squares: https://www.ebay.co.uk/itm/300772011310?var=600055717705 (should do both sides)
Ordinary door numbers (9 inch/23cm): https://www.ebay.co.uk/itm/184096272079
Dayglo yellow vinyl numbers (150mm high) for rear quarter windows: https://www.ebay.co.uk/itm/184102079778
Other sources are available, and providing these links is not an endorsement of those eBay sellers in any way. Just might be handy for those in a rush :)
Numbers are available at most BARC meetings if you know who to ask......
Bully, i'm not sure about them being transparent.
I don't think anyone would see them?
