How can a LED be flashed like a strobe, motion activated and installed outside to act as a security light? Answered

This is about home security.  I have posted another security question on single LEDs in the same category.

We have a remote house under construction at the end of a cul-de-sac. 

My idea was to create some type of motion-activated single flash strobe or LED burst of light.  This light would be installed at the cul-de-sac and the motion sensor could be further away.  I just want to create this big flash so that any one coming around in the wee hours has to decide if they just had their picture taken and do they want to go further.  The strobe would just flash once like a camera flash, not flashing repetitively.

So the final product would have to be weather and water proof.  The house is about 200' from the cul-de-sac but there are a number of empty, underground PVC conduits run from the house electrical panel which could be used to run out 120v or low voltage wiring.

I've looked everywhere on the net.  The closest I could find were cameras that are made to take flash photos of animals at night and are motion activated.

were you success in buying/ making anything? i have installed security camera's in my house. but would love to have a motion activated flash, which will scare any intruder and also will help me pause the video and get a good picture in case i ever have to. I am not an electronic person. so making something is out of question. Looked all over the internet. No luck.Thanks

 You can search for a motion circuit that will trigger a photographer's flash with the search terms "circuit motion flash trigger."   You can buy a detector-flash trigger for about $30 described at http://www.glolab.com/gct1/gct1.html.  

Cheap flashguns are available on eBay.
