This is the one that I have, and I LOVE it. It is very bright and sticks very nicely to my machine. It is a little bit pricey, but I bought one for $10 that was terrible, couldn't use it it was so dim. Also, don't buy the light brackets separately, I did that and then found that the brackets come with the light already.
