997 Fog Light Bulbs

Can you help please?

The rear fog lamp bulb is P21/4w. Can I change this to a P21/5w without issue?

Also, anyone changed these bulls to these without throwing a check light?

Twin filament fog light bulb? Curious. 21/5 sounds more like a stop/tail bulb.

Yup, twin filament. Mine has one filament failed so looking to replace but trying to work out if a) a 5w will work and b) if there is an led equivalent that will work.
