You have to buy what people call an "electronic" relay (even though the mechanical version is also electronic so to speak) which is to say it's solid state. The "mechanical" relays have a capacitor that charges and discharges. The charging/discharging rate is proportionally to the load it's driving. An incandescent bulb draws around 2-4 amps I'm guessing while the LEDs draw around 400mA per bulb. The mechanical relay doesn't work correctly for the LEDs because they are a smaller load and cause a faster charge/discharge rate ie fast blinking. The solid state relays switch at a constant rate independant of load and is why they are often needed when switching over to a LED system.
