Putting in a fuse with a larger amp rating will decrease the protection of the circuit, not increase it. In a 12 volt circuit, a 16 amp fuse would not open until the circuit was consuming about 180 watts. Think about how much heat a 180 watt light bulb would put out. Probably enough to start a fire. You know the MB's you see for sale cheap on E-Bay after a fire in the dashboard? I bet that's from putting a 25 amp fuse in place of a lower rated fuse for the blower motor. Putting in higher rated fuses can be very risky. Another question to ask yourself would be whether or not your insurance company would pay a claim if a protection device is defeated. They might be within their rights to decline to pay such a claim. I would urge you to use only the recommended fuse values.
