You can charge your smartphone while cycling or running with an accessory also designed to keep you alive on the road.

Sounds like a lot to ask of a battery pack, but the Boost Pack by BSEEN does both with a rather simple design.

The Boost is a belt pack with an LED light panel that stays lit or flashes. It also holds your smartphone and a lightweight 4000 mAH rechargeable travel battery pack to keep your phone charged.

A study by the National Highway Traffic Safety Administration reported that more than 4,000 pedestrians were killed by vehicles and 70,000 injured in 2012. While runners are in the pedestrian category, the report did not say what percentage were runners. Running groups have been promoting safety to prevent collisions and clothing and accessory manufacturers are making products that light up or use more reflective material.

BSEEN is trying to raise $25,000 on Indiegogo to bring the BSEEN to production. The campaign has raised about $6,000 with 56 days left.

For a donation of $35, an investor can get the Boost with the battery back. For $20, a backer can get a basic belt back, which has the LED lights with three settings but no phone charger. Early backers could also get some BSEEN LED slap bands, wrist bands that add extra light to your evening or early morning run.

The belt packs are made with a lightweight water-resistant material and include an adjustable waistband, a key clip, port for ear buds and a roomy internal pocket.

The California-based BSEEN, with the help of Trident Design in Columbus, Ohio, develops LED safety wear for outdoor sports.
