The light will only draw the amperage it requires. Put a 10-amp inline fuse right next to the battery on the circuit, just in case there's a short. Or, find a circuit in the underhood fuse box that gets constant 12V and use and add-a-fuse on that, rather than putting a wire directly to the positive terminal.
