It has a beautiful black anodized aluminum housing. At 70b lux it's bright enough for most cyclists in most conditions. The beam illuminates the road well both at a distance and close-up, so you won't miss the pothole that wasn't there yesterday. The IQ-XS automatically changes from a daytime beam to nighttime beam depending on ambient light levels. So you always have the optimal headlight beam.

The IQ-XS E has no switch. Nor does it have connections for a taillight. Your E Bike needs to have an On-Off switch for lights as well as connections for headlight and taillight.
