Default LED Tail Lights

So I decided to upgrade the old dim tail lights in the flat deck of the 2004 Dodge Ram 3500.
Now they flash like a strobe light, flasher indicator flashes rapidly and I get a lamp out message.
In the old days we just installed a heavy duty flasher relay, but now everything is read through the ECM.

Do I have to install some kind of resistor?

New unit: 2004 Ram Dually, Quad cab, Flat deck, 6 spd standard, ECM re-programmed by Harbour City Diesel 250 hp to the rear wheels on the dyno.

STOLEN: '98 Ram Dually quad cab; 4X4; auto with mystery switch; 4:10's; BHAF; 4" MBRP exhaust; 3K Governor spring kit; #5 plate; timing @15.5; 63/65/14 turbo; 90 hp injectors; Isspro pyro, boost & tranny temp gauges; DSS steering stabilizer; adjustable heavy duty track bar, Snow Water/Methanol Injection Tow-Max System.
