The measured head circumference decides the size, not the S/M/L label · review
An adult helmet with USB rechargeable front and rear lights, a detachable tinted lens, 10 vents and ASTM, CPSC, CE and EN1078 certification.
Our conclusion The most visible helmet here, if you accept less airflow.
Most lit helmets only have a rear lamp. The ILM adds a front one, which helps at junctions where a driver looks toward your head first.
ASTM, CPSC, CE and EN1078, a one-piece EPS and PC shell, USB rechargeable front and rear lights, 10 vents with rear cooling channels, a detachable tinted lens, a size adjuster, and a removable, washable mesh lining. The maker warns that an electronic helmet cannot be guaranteed to work perfectly and asks buyers to contact it if the light fails.
It is honest, and worth reading. The helmet’s protection comes from the foam and shell, not from the LED. A failed light does not make it unsafe, but it does remove the reason you paid more than for a plain helmet.
The listing has no lumen figure for the front light, so do not count on it to light a dark road. Ten vents is few, and on a hot day you will feel it on a longer climb.
| Lights | USB rechargeable, front and rear |
|---|---|
| Standards | ASTM, CPSC, CE and EN1078 stated |
| Vents | 10 |
| Shell | One-piece EPS and PC |
| Eyewear | Detachable tinted lens |
| Lining | Removable, washable mesh |
No output figure appears in the bullets we read, so treat it as a be-seen light and keep a real headlight on the bike.
ILM calls the lens eyeglass friendly.
