fuse rating for fog lights

[BEEMA]

I just bought a set of Wunderlich fog lights they are rated at 12v/40w4000Lm per head light which I think is approx 3.3 amp draw.. they are plug and play using the trigger wire from the on board socket 12 v power is via in-line fuse via battery terminals.. via a on off switch on bars.. but not sure what size mini blade fuse to use.. any one fitted fog with the same power output and what size fuse did you use.. fog lights came with a in-line 30 amp mini blade fuse.. but I'm thinking a 10 or 15 amp to be on the safe side.. or should the 30 amp be fine?

Match the fuse to the size of the wire.
