The installation of the NIGHTLUX BLM does not require any tools and only takes a few minutes to complete! Simply loosen the adjustment strap on the BLM mount, wrap it around the bicycle handlebar, and tighten the strap until it fits the handlebar snug. The BLM fits handlebars up to 40 mm in diameter. High Quality Light Options - The NIGHTLUX BLM uses CREE LED lights with multiple setting options. Choose between two flash settings and two brightness settings to fit your child's needs. The BLM also shines with 115 lumens in a 180 degree field of view so your child can see everything in front of them as they ride! The power button lights up blue to indicate the BLM has full battery power and changes to red when the batteries need to be replaced. You can feel assured your child will be safe when riding in the dark! Weather Resistant - The NIGHTLUX BLM can handle most harsh weather conditions.
