I bought them for my bicycle...Little did I know, they are just a little too big for my bicycle and thats makes them even cooler than I thought. I didn't read the whole discription and that's all on me. Believe me, it's just fine that I did that because it was like I bought myself a presant! SURPRIZE!!! I remember wishing they were a tad bit bigger. Surprize they were just what I had wished for. They come in a pair, they are very bright, attractive, and a win/win situation. They are easy enough for a gal like me, to install on a pull behind trailer or an ATV, or anything that you would pull and needs directionals. Signals left, right, back-up, and stop. Anyhow you use them, communication always leads to success. 5 Stars for promoting safety!
