I think the car of the month from Amazen Toys has the amber high beams.
I remeber 20+ years ago some of the guys in the autoshop class in high school had them because the autoshop teacher "borrowed" one of those big DPW signs that had a black background and had a huge blinking yellow arrow made up of headlight sized lights. He popped them out and gave them to the guys in the autoshop so they used them for high beam lights.
