led tail lights

[apachedaddy]

Trying to do my homework on LED tail lights. The tail light seems pretty stright fowrword. But this is what the company that is selling the light assy says, "Due to the low amp draw and no heat produced by LED lights, some of the time a stock 522 flasher will not cycle/flash. We highly recommend our no load electronic flasher to solve this problem". Does this sound right and is there any other hidden items i may need? Thank you for your help on this..
