What bulbs in climate control?

[Coxy]

My windscreen button and one next to it aren't illuminated, and it annoys me! What bulbs will they be please and easy to replace?

Thanks

Same as the dash bulbs, the twist in jobbies.
This'll give you an idea.

Thanks, so those exact ones would do? Do they need to be coloured or they shine through coloured film?

Yep, those will do the job. And as you say, clear bulbs.
