In addition to having a Back-Off Brake-Light Modulator, I just ordered these red LED strobes (check out the video!). I'm planning on installing them on the top of my license plate.
Speaking of brake lights, how soon do your come on? A while back, I noticed, while driving at night, and gently slowing (almost coasting) for a stop light, that my brake light wasn't coming on! The rear brake wasn't as bad as the front, and the rear brake is adjustable, but I finally adjusted it (it only took me 40,000 miles! ). I solved the problem with the front brake by using a dremel to grind down the spring-loaded pin a bit so it engages the brake light as soon as the brakes engage.
Though I've never been rear-ended, and I'm not sure statistically how often it actually happens to motorcycles, I'm taking measures to reduce the odds of it happening to me!
I'll see if I can post video of it once they're installed.
