Solar powered blinking Led (with photo switch)

I was wondering if anyone has or will post an instructable showing how to build a self-contained solar/rechargeable blinking LED (or LEDs) 

I have a telephone pole I would like to have illuminated for oncoming traffic.  Reflective tape isn't cutting it.  I was thinking a LED strip that blinked would be a better "notice" to drivers.

It would have to be self-contained and powered given the location, hence the solar/rechargeable aspect.  It would also have to turn on at dusk and off at dawn. (off when light out, on when dark, so a photo switch needed)

Any ideas how this can be done?  I was thinking hacking a solar powered yard light to power a LED strip but I have no idea how the electronic parts work or if the charge is enough to do so.  I am sure there are parts in one of those lights that I can use.  Harbor Freight is my buddy.

Any help appreciated.

A search of the projects on Instructables would give you a great start. There are project on making LEDs blink, solar powered ones, and solar / light activated ones. It sholdn't be hard to hack the ideas together and get what you need. I am wondering though, at night if the LEDs, even ultra brights, could be seen in headlights?

We have some of these in our yard. Now they're not blinking LEDs but they're solar powered so they might be a good place to start. I don't know just a suggestion. You could Take a few apart and probably set up a circut to your liking. Hope that helps
