Yes you can
You need to check the amp rating of the lamp that is already installed.
The switch rating should be higher or equal or you can use the relay you have in place.
Attach the Light circuit to the "Load" side of the relay. Run wire from power source's Hot supply to one of the relays load terminals (use fog fuse as power source, it is hot all the time). Connect the relays other load terminal to the light closest to it. Connect the remaining connection on the light to one of the connections on the other light. Connect the second light's remaining connection to the negative side of the power source.
Connect the switch. Run wire from a power source to one of the "Control" terminals on the relay. Connect the other terminal to the switch. Connect the remaining switch terminal to the negative of the power source (negative side of fog fuse).
Start car and test. If selected sources fuse blows, replace and try connecting to another source.
