More light with Less power
Motorcycle headlights usually leave a lot to be desired when it comes to actually seeing where you are going in the dark. This is especially true of the DR650. With my eyes no longer working like they did when I was 20 (or even when I was 40) getting more light in front of the bike is more important than ever.
One of the first things I did was to replace the stock 60/55 H4 bulb with a brighter 100/80 bulb. That helped a little, but riding on an unfamiliar road in the dark was still no fun. In addition, the DR doesn't have much extra electrical capacity so running a higher wattage bulb means not running any heated riding gear. I think I've found very good solution in a combination of products - the Electrosport HID light kit and the VisionX Solstice LED lights.
There is a problem with many HID kits. HID bulbs have an arc instead of a filament. This means the placement and shape of the light source can have a detrimental effect on the light pattern made by the headlight lens and reflector. The wrong combination will blind oncoming traffic. Many HID kits only have one fixed beam. Our Electrosport kit has a solenoid that moves the bulb capsule from the low beam position to the high beam position.
Look below to see some comparison photos showing the relative light output. All these photos were taken with a Canon EOS Rebel XTi set at ISO 1600, 1/25 second at F8.0 The images have not been manipulated other than to resize them.
