Motorcyclists are finding that a motorcycle headlight modulator reduces the likelihood of the biker getting struck by cars whose drivers have failed to see the approaching bike. Bike owners who have yet to install one of these modulators can usually install one without the cost of having to pay a bike shop to do the job for them. If you plan to install one of these modulators on your bike, here are seven tips that will be of help.
Tip 1 – Choose the Right Modulator
When evaluating prospective modulators, take time to consider things such as wiring. Some modulators do not require wire splicing. Others do. If you are not comfortable with wiring procedures, or if you don't have the tools needed to do this splicing, you should consider a modulator that does not require splicing. Also, consider the number of headlight bulbs each modulator will power. If you bike operates two bulbs, and if you want both bulbs to be modulated, be sure your new modulator will power both bulbs.
Tip 2 – HID (High Intensity Discharge) Headlights
Headlight modulators are typically not compatible with HID headlights. So, take this into account when you are choosing a modulator. If your bike's headlight operates with two bulbs, one for bright and one for dim, and if they are HID, it may be possible for you to use a standard bulb with modulator and an HID light together, rather than 2 HID lights.
Tip 3 – Bike Fairings and Modulator Installation
You will need access the back side of the headlight assembly to install your modulator, so you'll need to remove the lower side fairing. You can leave the front fairing attached and still install the modulator, but you'll find it much easier to remove it. Locate the plug/adapters, then tug them loose to disconnect headlights and wiring harness.
Tip 4 – Choose the Best Place for your Modulator
Before attaching your new modulator to your bike, examine the bike for the best place to attach the modulator, a place where it is likely to be out of the way and where it is not likely to get knocked loose. One place to consider is on the frame, just behind the bike's instruments. Once you decide where to install the modulator, you should be able to attach it tightly by using zip ties. But if you tuck wires into these ties, be careful not to pull the ties so tight that it will damage the wire or pull the sheathing away, bare the wire, and create a potential short in the wiring.
Tip 5 – Attach the daylight sensor
To operate as it should, you'll need to install the daylight sensor where the sky is within view of the sensor. If you attach it to the front brake cable take care to give the sensor wire slack enough that you'll be able to fully turn the handlebars.
Tip 6 – Connect to Wiring Harness
Locate the wring harness connector and connect it with the modulator's male connector.
Tip 7 – Reattach Fairings
Reconnect fairings. Connect modulated light to unused female modulator plug. Then, turn on the bike and test the lights and modulator.
