That is a lot of money, if it is just for the LEDs. Even the best GTR LEDs which I use, which are warranted for life, cost less than $400 for the entire set of rear LEDs, including the backup LEDs.
If it is for an entire pair of rear light housings containing LEDs, I would still say that is a lot of money.
