Before You Decide
Confirm the SEEMEE 50 V2.0 model, the 50 lumen output and the IPX6 rating before choosing an offer. If you want the LightSync function, check that you also have a compatible Magicshine ALLTY light and MJ-6558 remote. Review the mounting position on your bike before purchase.
Understanding the IPX6 Rating
IPX6 describes protection against powerful water jets; it is not an immersion rating. If your rides may involve submersion, check the manufacturer’s guidance rather than assuming this rating covers it.
