From st3v3; << Would it be a bad idea to install them on the front of the machine also ? >>
It's a good idea only if your jurisdiction permits a pulsating light *other than* a headlight. There are alternatives to the Hyperlight for the front. One that comes to mind illuminates your amber front turn signals constantly until you activate your turn signal, then goes to blinking mode for the one signaling the direction you wish to turn. (Forgive me for not knowing the brand name off the top of my addled head.)
From Semper Gumby: << I also have reflective tape on the back of my white helmet (white and red). All my clothing except my dry rider rain suit has refective 3M material on it. It is black but when light hits it it lights up like a mirror. >>
I have a silver helmet and put red reflective triangles and a rectangle in a pattern on the rear. White reflective rectangle on the sides, and white reflective triangles in a shark-tooth pattern below the face shield in front.
Each of my touring cases has one 2" wide 3M Diamond white strip running parallel with the general horizontal lines of the bike (extending essentially the width of the case). The 3M diamond tape is great stuff; it's brilliant silver/white reflecting > 45° off the perpendicular viewing axis, for > 90° total reflectivity — from directly behind, beyond 45° on either side. It comes in red, also. See below.
In addition, I put, on the front and rear of each touring case, panels of the 3m reflective material that Gumby mentioned. I like it, also.
For increased reflectivity, I modified a wide advertising dealer-advertising rear license bracket as follows: On one side, I put 3 horizontal stripes of the 2" diamond tape — red/white/red, so that the stripes surround the license plate. On the back of this bracked, I put a solid panel of the black/mirror 3M material, so that it reflects when the bike is view from the front.
I *still* don't have photos to post, and I won't be able to do it this weekend. First good day I'm not at the office, I plan to do a photo shoot of the bike, irrespective whether I've had time to give it a bath.
I want to start on the lighting modifications, but I'm still researching. I'm quite conservative about hacking an old but working electrical system. Besides, I'm not riding at night until I get my eyes fixed. (That's a work in progress, also.)
Doubtless a lot of vendors sell the reflectives. I found the 3M Diamond tape at ridesafer.com, which has a lot of good stuff. I bought the 3M black/silver material in 8"x10" sheets from Bob's. It comes prepacked; 3 sheets are nearly $20 plus S&H. (Measure twice, cut once!
