This article is based on information that was clearly explained in this link:

I modified the circuit to replace the R2 resistor with a diode to improve the performance and reliability of the circuit in the link above.
Step 1: Design the Circuit
I used the PSpice student edition software version 9.1:
The light bulb can be replaced with a moderate current LED lighting source.
Step 2: Simulations
Transient (relay input voltage):
Transient (load voltage):
Conclusion
My circuit was not tested. However, I believe it can work.
