Question: Do these have a "flash" setting?
Document: I really like these lights, I wasn't too sure on how bright they are and they impressed me, they even have a blinking setting on them, I am going to have fun with this product, I bought two of them for my windows.
Party Lights! We use these when we hike/camp in the Grand Canyon since there are no fires allowed. Also hang them around my daughters trampoline net so she can jump at night. They provide a lot of light and last forever! Still haven't changed batteries and I've camped 3 times with them and my daughter has left them on overnight numerous times on accident after jumping on her trampoline. Blinking setting is pretty cool too. Great product!
use this on my golf cart..perfect length to go around the roof. Nice for the holidays or anytime as they are bluey-white colour
they didn't work at all. Only half of the lights would light up and only lasted about 2 minutes. VERY POOR product.
these lights are the ticket! Remember that they are battery operated and NOT AC powered, and they aren't to illuminate an entire room, you get what your expecting. They do a great job for a small tree or as I used them for a small picture box.
i ordered this product from three different companies - 2 1/2 weeks before a fundraiser i was hosting. the promised date was a couple of days before the event, but they showed up two weeks AFTER. four weeks for shipment is unreasonable, especially since i received this on time one of the other sellers. buyer beware - shipment date was the day after i ordered, but since it apparently came from china, it takes SO long.
Worked for our project. Bought 4 strings just in case 1 string came DOA but they all worked great. Well made.
When I was looking for blue led lights, I was looking for lights that &#34;Plugged into an Outlet&#34;. I didn't realize, until after I received them that they were battery powered.Who would want lights that you have to keep replacing batteries??!! Not me, so I'm stuck with them. I don't recommend this product at all! !
We use these camping they worked GREAT!! The batteries lasted 5 nights.
Was able to highlight the sign in board for my granddaughter's sweet sixteen party so that her guest could write her messages
