HID light trick - did you know this?
So, here is something I found out a few weeks ago - and I submit it for your otherwise bored entertainment only. No gripes, no poking fun at BMW engineers, no angry dealer rant, just pure entertainment value only.
You all know that the HID headlamp won't come on unless the engine is started,... right?
Well,... that's not entirely true.
I have a downward sloped driveway from street to garage, and I always leave the key in the ignition. In the mornings, I push the K out the door, put on my gear, turn the ignition on, start the bike, and then the HID lamp lights up, and away I go. I can easily see this at 5:00am and I'm sure the neighbor's kids can too in their dark bedrooms across the street.
In the afternoons when I come home from work, I drive the bike down the driveway, turn it uphill with the engine still running, drop the kickstand and the engine dies. Leaving the ignition on, I then open the garage door (need remote in pocket), then remount, put the sidestand up, pull in the clutch (or put it in neutral), and ride it backwards into the garage with the ignition still on, but the engine off.
Guess what? As I start to roll the bike into the garage, the HID comes back on. Stop the motion, and the HID extinguishes its self. Move on, stop off. Move on, stop off. Engine off, transmission in neutral or clutch in so no movement in the transmission, still works.
It seems as long as the ignition switch is on, the electrical system will ignite the ballast if the wheels are turning, or maybe it's the FD turning. I don't know. What's the deal with that?
Now be honest, how many of you knew this?
It doesn't need much speed, just a slow motion. Heck I can't run it up the driveway by hand if I wanted to, and it was only after the daylight hours have gotten shorter (damn it) that I noticed this.
Guess I won't try sneeking in after hours with the engine off after all. The dang headlight will give me away. Some DOT requirement for motorcycles?
