Flashing Red Arrow Light

Bright white light is very bright. Red/red-flashing light is cool -- not sure if I'll ever use it. Good fit and balance (with batteries in back). Lightweight and comfortable. Looks suitably geeky. Very happy with my purchase.

This is a very nice headlamp, without two levels of white light, a red light and a flashing red light.  Having the battery pack on the back makes it much easier to balance and the straps are adjustable over a wide range.

My APC UPS sounded off every few hours with beeps and a flashing red light to let me know it was time to replace the battery. I ordered online and the battery arrived sooner than expected. I installed it and it's been working fine since. The part I especially like, I didn't have to shut everything off to install.

but it is unsettling to have the upstream light flashing

I keep the Poly-Steel 700 in my truck because of the fact it has the red flashing light on it. If I would have trouble I can just turn it on and stick it to the truck since it also has a magnet. It has the zoom on the front end and all the lights are bright. I have several Coast lights and all of them are high quality and well designed. I will always be a Coast customer. The warranty and customer service is second to none.

I bought this so I could be in more pictures with my kids! Totally beats running back and forth from the tripod to race the flashing red light!

Brighter than I expected on high white mode. We must cycle through all 5 modes, but white has 3, than red (flashing red is included). I hand hold it to cross the street so people can see me and I don't hit the curb. Also helps to avoid puddles in the street and toys in the driveway! AA convenience is King!!

Nice heavy flashlight with some nice features, the magnet on the end, the side lights, the red flashing lights. I keep one in my car and one by my desk!

This is an easy-to-use polarizer that comes in a nice, solid case. For bird photography it helps get the glare off the water and for birds in trees it helps get some of the sheen off the leaves, increasing the depth of color. Like all polarizers it takes away light, so it's more useful in brighter light. It snaps in and out reasonably easy - not effortless - but good. If Canon had put round bevels on some of the edges it might self-align better when installing but that would be extra credit. I particularly like the arrow on top showing which way faces front. I wish the default filter that comes with the 500mm f/4 II also had this arrow. I'll probably draw one on. If you shoot birds on water this filter is an absolute must.

Just enough red light to see.
