I would also recommend improving the lighting. I had several incidents when I first got mine of people pulling out from side roads who had apparently not seen me. I added amber/yellow LED fog lights (High Noon started a good thread on this in the archive here), and wired them to come on with the ignition as daytime running lights. I also upgraded to the JW Speaker headlights (in the US you can buy some "retro" looking ones) and drive with them on all the time, I modified the rear reflectors to be running/brake lights (again there is a thread here on doing this), as well as mounting additional high-level lights on the back of the headrest that act as turn signals, running lights, and as high-level brake lights with a flasher. These make me more obvious from behind to the pickup truck drivers!
