Bicycle Head Light ?

[pptouring]

1.3 lbs! Wow it really did not feel that heavy. The hub is always putting out energy, so it would depend on your lights. The lights we have (Busch & Müller Lumotec IQ Cyo R Senso Plus) have a built in sensor that detects low level light and will come on/off automatically if you have the switch in that position. The lights will come on if you travel through a tunnel and turn themselves off after you exit it.  If there is a heavy overcast the lights will come on and naturally as the sun sets they come on too.  You can also run the lights all the time or turn the switch to OFF and they'll never come on. The "Plus" means the light has a built in capacitor and will remain on for 5-8 minutes after stopping. The e-Werk wires directly into the hub so it is always ready to output electricity to your devices such as GPS, cell phone, etc... I use my Garmin GPS and the setup is great. I still require batteries because when I stop moving forward my GPS automatically switches over to them and then switches back to external power after moving. Unfortunately, I still require regular batteries because my GPS is unable to recharge them, but they last a lot, lot longer with the e-Werk.

I bought two headlights in Yemen for one dollar each. One has nine LED bulbs in it, and the other has only one.
Use your headlight for what you do at night in camp and such. Strap on an LED flashlight. I take lights on tour. Not having the detailed maps on ACA, I have found myself at times cycling late into the night with sheer rock walls going up on one side of the road, and sheer rock walls falling away on the other side, and absolutely no place to stop and sleep for hours. Lights are a good thing to have, and there is no telling exactly how much you might be using them. Be sure to have a really bright back light, because if scudgemo comes along half in the bag and five minutes away from his last visit to the crack house, he will most likely swerve over and hit you from the rear.
