Get the headlight modulator. I have the one from
Comagination - it's a five-minute install, costs only around $45.00 and is the best thing you can do to keep people out of your way on the bike.
A high percentage of bike accidents are left turns, and pull-outs in front of bikes - using the modulator on two-lane roads makes people see you - plain and simple.
Turn it off when you're close behind people or on the super-slab... I've never had any issues with mine, just remember to try not to be an asshole and you're all set.
And really, who gives a ripe **** if it pisses off cagers? They're out to kill you anyway, by force of sheer ignorance. Get yourself out there and be seen - stay alive.
Of course, that doesn't mean they can't stop you, cite you and force you to go to court to prove your case...
Print this out and keep it with your registration card. It's not guarantee, but if you can show it to the guy on the side of the road and remember to be polite to Mr. (or Ms.) Police officer, you've got a good chance to make your case on the side of the highway.
I've thought about getting a couple of
these (or something similar) and mounting them in the side-cases, with a detachable connector so I can still take the bags off, but I've not gotten any further than the "think about it" stage.
