These are bare addressable 1 meter long RGB LED strips that come packed with 60 WS2812s per meter. As these are bare LED strips that have no protective coating, your project won't be water proof but there is access to each WS2812 LED and each strip length can be easily modified. You will be able to control each LED RGB individually giving you the ability to create cool lighting effects for your car or perhaps under cabinet lighting in your kitchen!
Note: These come in 1M segments on a reel. They are preterminated with 0.1" spaced 3-pin connectors as well as a 2 wire power connector, as shown in the pictures.
