Lighted Trailer hitch Cover that has Tail Light, Brake Light, and Turn Signal Functions

Question:

I like that the product signals with the turn right turn signal, but why doesnt it blink when the left turn signal is applied? I think it should blink with either left or right turn signals, it would make it a safer product not only for the consumer but the people behind you as well. please advise.

Usually, people want the exact opposite; for it not to blink with either turn signal. The reason that it blinks with just the right turn signal is because the 4-Way connector for a trailer has combined brake and turn signals and only one wire and a ground is used to power the light, in this case the green right turn/brake light wire.
