It depends on how much current your light bulbs use. If the current is low then why bother changing the value of each current-limiting and sensing resistor connected to the LEDs. A low current light bulb is dimmer than an LED.

If your light bulbs use a higher current so they get nice and hot then the entire circuit must be re-designed.
