Summary of Specs: 300 Lumen 3.5 Hours Lighting Time Suitable for Most Skateboards Type C Charging Interface 2 Hours Charging Time The brand new BACKFIRE Gen II Lights are our latest skateboard accessory, created based upon the feedback from our Gen I Light users and the E-skate community. It features two 300 lumen lights per set with 3.5 hours of lighting time, enough for any night group ride or commute. The mounting mechanism of our Gen 2 Lights, based on feedback, has been moved from the top of the deck to the bottom, and are placed aside the truck base. The triple-split Type-C cable included also allows you to charge both lights and the BACKFIRE remote simultaneously, which makes it two cables less for you to worry about. Disclaimer: This light currently might not fit the Ranger X1 or X2, and Mini for directly installation under the deck.  You will need a riser under the truck and longer bolts if necessary to install the light under the Ranger deck.
