Advocacy & Safety - OK to have reflector not be on the seat post?

I just realized that with my rear pack (which is a large topeak saddle pack) fully expanded to fit a thin wind breaker and a couple of energy bars, there isn't enough visibility below to see both my rear reflector and rear blinker. So I decided to move the blinker down as low as possible on the seat post and move the rear reflector to the left seat stay where the brake calip's are (since I'm mostly on the right side of the road).
Does anyone know legally if this is allowed and if I have to put another one on the right seat stay?

I think you need to check your state laws. Most only specify that they need to be visible from a certain distance at certain angles and don't mandate exact location on the bike but then again, I remember you posting an excerpt from your lawbooks that require reflectors on the spokes of your wheels so...

I have a Topeak Saddle Bag to which I attach my rear light (it has a place where I can clip one on). It doesn't seem to have provided me with a problem as yet.

Makes sense to me. I always put some reflector or reflective tape as low on the bike as possible because car headlights will shine more brightly on things closer to the ground when they are using low-beams.

Lights, however, should be higher so they are more visible.

Hmm.. after reading through that law again, it doesn't say anywhere that I need a front or rear reflector, just side reflectors on my wheels which cover side visibility. As for front and rear, lights are mandated, I guess whoever wrote the law realized that if you have a blinker and a front light visible for 500 some odd feet that the reflectors are essentially dead weight anyway, unless your batteries go dead...

I've lost 2 blinkers on my topeak bag, the little loop on the back is so thick that the clip barely fits and causes it to pop out. On most packs I've used, the blinker's either dangling and aimed too far up or down.

California traditionally required a front light, plus a rear-facing red reflector. During the bike boom, CPSC-approved pedal reflectors, a front reflector, and side reflectors were added to the mix. On each of the Peugeots, I have a headlight, an old-fashioned clamp-on red reflector on the left stay, a red LED blinkie on the rear rack, and an orange/yellow LED blinkie on my backpack. I have no pedal reflectors because they obstruct the rear-facing flip-tab on road quill pedals with toeclips and cannot even be mounted on most clipless systems. I do not have wheel reflectors because they throw the wheels out of balance and do not materially contribute to my safety. (By the way, I always wear bright colors during the day, and light colors at night.) Since I never ride the Bianchi at night, it has no reflectors.
