You blow a light bulb due to over voltage not over current because it is the voltage across the light bulb that determines the current through it (assuming enough is available). So, I would just put two 25 or 40 watt bulbs in series.... I.E. with one wire into one and out, then into the other and out, with the second wire on a switch or something... just not in parallel.. this way you will halve the voltage across each bulb and should be OK...
