So I recently purchased a cateye HL-EL 500 from Performance bikes. When I had it at home I put the batteries in and it worked... oh boy! Today was my first ride with the light on the handlebars. It was not since I leave home in the daylight. My ride in was around 6 miles. I didn't do anything crazy... didn't run over any dead animals or large rocks. I didn't hop any curbs. However when I was messing with bike at lunch I tried to turn it on and it wouldn't. I assumed I must have left it on in my bag and the batteries were dead. However, when I tested the batteries on another light worked fine. I do have another light to get home so I'm alright there... I was just wondering if anyone knows of any problems with this light or has heard of problems? If not I'll just take this back and assume this one was defective and get another.

Thanks. I appreciate any help that can be offered.
