A tail (stop) light bulb is an 1157. Change the bulbs to the proper type, if in fact you are using 1156s in error.
Not all modulators are compatible with LEDs. Confirm that yours is. If not, use of regular (filament) bulbs, installation of a load equalizer, and/or replacement with an LED-specific modulator, may be necessary.
(Note that a load equalizer is usually only required when replacing original, filament-type 1156 turn signal bulbs with LEDs.)
Recheck the installation wiring. The proper wires (ID'd by color) must be tapped when a modulator is installed; there's no margin of error here.
