There were no instructions with these. There is an off position and a 1 and a 2 choice. Only one is working. They flash on and off and have a lot of red in it which makes it look like a Christmas decoration. Not at all happy with this purchase.

one worked one night and now neither is working

These are waste of money, I tried everything but did not work. I threw the box away so I can not return them.

They don’t work properly. I’m very disappointed

In complete light and do not work.

Updated review: I had this installed and it looked pretty atfirst and I realized that just within a couple of weeks that the lights only last for about 2-3 hours at night and then it goes off. Such a waste of money! I wish I could return this product. CHEAPLY made!!!
