I made a little extension for the headlight bulb so I could swap the harness in and out without taking the headlight bucket apart.
I then propped the camera (with a tripod) on the tank/bars of the bike and took the pictures.
These are unretouched photos I took in front of my house at about midnight, using an Olympus D490-zoom digital camera, using only the automatic settings.
All pictures were taken with the stock bulb (60/55 watts), and using only the low beam.
There's two sets, the first is with the engine off, the second with the engine running.
