Answers to the most common questions about the Kepler Ebike Headlight: voltage compatibility, fork and handlebar mounting, beam cutoff, and what 350 lumens means on the path.
Wiring and voltage questions
- Will the Kepler Ebike Headlight work with my e-bike's electrical system?
- The supplied specifications say it works with any 6V-15V e-bike system. Check your bike's light output or accessory port voltage before buying; if your system falls outside that range, this light is not confirmed to be compatible.
- Does the light come with a wiring harness or connector?
- The supplied information lists the light, fork mount, handlebar mount, and steel fork-crown bracket, but does not confirm a wiring harness or connector type. Ask the seller or check your bike's existing light connector before assuming a plug-and-play fit.
- Can I wire it directly to the e-bike battery?
- The supplied information does not include wiring instructions or a confirmed connection method. Do not splice or connect the light to a battery without guidance from the manufacturer or a qualified e-bike technician.
Mounting questions
- Where can I mount the Kepler Ebike Headlight?
- The supplied details confirm both fork and handlebar mounts are included, and the light mounts to the fork crown with a steel bracket. Choose the position that gives the beam a clear path ahead without being blocked by cables or a bag.
- Will the fork mount fit my fork?
- The catalog confirms a steel fork-crown bracket is included, but does not supply fork-crown dimensions or a list of compatible fork models. Measure your fork crown and compare it with the bracket before installation.
- Can I use the handlebar mount instead of the fork mount?
- Yes, a handlebar mount is included. Handlebar mounting is often simpler for riders who switch between bikes, but check that the light clears your brake and shift cables and does not interfere with a handlebar bag.
Visibility and beam questions
- How bright is the Kepler Ebike Headlight?
- The supplied specification is 350 lumens. That is enough for being seen and for lighting the path directly ahead in many urban and path settings, but the catalog does not provide a beam distance or runtime figure, so judge it against your own riding conditions.
- Will it blind oncoming riders or drivers?
- The precision lens focuses the beam onto the path in front of you, and the light features a cut-off beam intended not to blind oncoming riders. Aim the housing so the cutoff sits below the horizon line.
- Is the aluminum alloy body important?
- The catalog describes the housing as aluminum alloy, which is a durable material for a light that lives on the fork or bar. The supplied information does not include a weatherproof rating, so avoid treating it as submersible or storm-rated.
