Seem to work well

It has been snowing so much in NY. I haven’t got a chance to use the bike and helmet. I tried the helmet and fit well. I like the light on the helmet especially if choose to ride at night or dusk.

Light failed in one week

I purchased grips and a CM-4 helmet. Both products are great except the light on the helmet failed after only a little over one week of use. I figured it might be the batteries. I changed the batteries but the light is still malfunctioning. I contacted customer service and am still waiting for a response, but an email asking me to review my purchases arrived in the meantime, so I’m doing the review sequentially. � I’d like just a replacement light if possible, instead of having to return an otherwise fully functioning helmet.
