MAXXHAUL 70429 Trailer Hitch Cover with 12 LEDs Brake Light

I bought a tail light/brake light unit and it disabled my back up camera. Does anyone know if the brake light only unit disables a back up camera?

Does it come with hitch pin and clip? if so how long? need it to fit 2011 toyota tacom oem receiver.

is a 1 1/4" trailer hitch cover with lights available ??

Does it blinks 3x's before going solid on?
