Why We Like The ESC-350 E-Lume Light Combo

Serfas' ESC-350 E-Lume Light Combo is a practical light set for our bike that both keeps us seen and lights our way. The front headlight, the E-Lume, runs for up to 80 hours with 350 lumens of output. The Cosmo 15 on the rear features IPX3 water resistance and a last mode memory feature that always remembers where we left off. We like that this set features a daytime flash mode and a USB rechargeable Li-Ion battery for convenient charging.
