High-visibility rear light
70% of cyclist fatalities are from behind. A bright, daylight-visible rear light is non-negotiable — day or night.
Daytime running lights (DRL) reduce cyclist crash rates by an estimated 19% according to the Danish road safety council. Look for at least 50 lumens in solid mode, a daylight pulse mode, and good side visibility. Pair with a Garmin Varia rear radar if you ride busy roads.
USB-C is standard, but a second rear light (one on the seatpost, one on the helmet or pannier) is the cheapest safety upgrade you can make.

Pro tips from our test team
- Use daylight pulse mode day and night — it doubles your detection distance.
- Run two rear lights on different modes. If one fails or batteries die, you're still seen.
- If you wear a helmet light, point it slightly down — it draws drivers' eyes to your road position.
