Frequently Asked Questions

Q. Why is the light sensor important?
A. Federal law requires a sensor to stop the headlight modulation automatically when it becomes too dark. This is to prevent blinding on-coming traffic to avoid an accident. Modulating a headlight without this safety requirement violates the law and takes a huge liability chance which might result from an accident.

My turn signal lights dim with the headlight modulation?

A. This condition can happen when installing a high wattage bulb that is greater than the bike's manufacturer recommends. The bike's wiring harness and switchgear is most likely undersized to supply the extra current required by the new bulb. A solution is to add a solid-state "relay" kit. Also, an undersized or failing alternator/generator or weak battery can case this issue with any bulb.
What type of bulb do I have on my bike?

A. Determine what type of female bulb connector you have. You can check your bike's manual, visually inspect your bulb, or call your local motorcycle parts dealer and ask for what replacement bulb type fits your bike. Most bikes use the 3-pin H4 bulb (high and low beams in one bulb) or the 2-pin H7 bulb. See bulb pictures.
Q. Why does the VisiPath headlight modulator not have a "shade delay"?
A. Federal regulations do NOT allow for any delay when surrounding light falls below a specified level.
Q. Why is the VisiPath modulator module designed not to mount directly onto the bulb?
A. Two reasons. First to give maximum mounting flexibility for bikes with small headlight housing with tight space. Second to avoid the bulb's high heat from degrading the modulator components.
Q. How does the daylight sensor mount? Any drilling?
A. After plugging-in the modulator (no wire slicing) you route the sensor wire from the modulator out through the headlight housing existing cable opening and wire tie (supplied) it to one of bike's handlebar cables. The sensor wire is plenty long for flexibility. The brake or throttle cable works fine. There is no drilling.
Q. I have a very small headlight housing will your modulator fit inside?
A. In most cases yes. The VisiPath modulators are very small. The modulator can also be mounted outside the headlight housing but this is the exception. Fits inside most headlight housings.
Q. Will the modulator or sensor visually detract from my bike?
A. Not really. Remember the modulator usually sits inside the headlight housing and is not visible. If mounted outside the housing it is small and hard to notice. After the sensor in mounted to a handlebar cable if you ask a friend to find it s/he will usually say "where is it?", even if you point to the sensor's location.
Q. How effective is a modulator?
A. It has been proven that a flashing light is more visible than one steady on. That is one reason why the U.S. Federal DOT has legalized headlight modulators for safety. Its been reported that most motorcycle accidents involve front end collisions. What's your safety worth?
Q. Can I connect two single headlight modulators instead of using a dual unit?
A. The dual headlight modulator keeps the two headlights modulating in sync. This is a Federal DOT requirement because alternating or wigwag headlight modulation is reserved for public safety vehicles like police, fire, etc. You don't want to get a ticket.
Q. Can I use a single headlight modulator on a dual headlight bike?
A. Yes. It's best to place the single modulator on a hi-beam bulb which gives better visibility. The second bulb would operate as normal.

Q. Will the VisiPath headlight modulator work with Halogen and Xenon bulbs?
A. Yes.

Q. Will the headlight modulator shorten my bulb's life?
A. In our many years of experience no. The bulb's life will remain about the same. There are no known reports of premature bulb failure we could find. If you believe this is still a concern then consider this: a typical replacement halogen bulb costs about $8. Given the bulb's normal operating life is 4 years then the dollar cost over the life of the bulb is $8 / 4(yrs) = $2(per yr). Now let us assume that modulating will shorten the life by 25% (
fictitious), then the extra total loss over the bulb life would be $2(per 4 years). That's CHEAP insurance to avoid a head-on accident and the high medical bills if you survive.
Q. Will my bike's headlight "pass" flash optional feature need to be disconnected?
A. The pass flash battery positive wire going to the bulb needs to be moved and connected to the modulator input, to another bulb, or disconnected.
Q. Is low beam modulation supported by the manufacturer or seller?
A. No. Manufacturer/seller only supports default high beam modulation installation. If user chooses to modulate low beam they assume self support.
Q. The modulator or brake flasher is not operating correctly when the engine is reved up.
A. Check the voltage regulator for spikes using an oscilloscope (multi-meter or std dealer test equipment will not show voltage spikes). The voltage required by our electronic parts is maximum 15 VDC.
