Lumos made their name on smart helmet lighting, and the Sonorus is the fullest expression of that expertise yet: a gyro-activated brake light system, front and rear turn signals, and near-360-degree LED visibility that holds up in real-world riding conditions. To round it out, there is a MIPS-certified shell and replaceable electronics module, as well as a mesh intercom system that keeps up to 15 riders connected. The intercom works well in line-of-sight conditions but falls short of the advertised one-mile range claim, which is the main drawback of this tech-packed product.
