I'm guessing it will be OK.
The electronics basically look for either no current flow (bulb flow) or current flowing (OK).
Otherwise, as long as it's within the switching capacity of the MOSFETS, you're OK. IIRC you're good for adding another pair of bulbs, so as long as you're not drawing more than a couple of amps for the sensors you should be good to go.
I can double check the MOSFET switching capacity if you want.
