 How to look for new planets

I think that instead of using all the expensive telescope equipment with precision lens and so on. That somebody should just make a huge freakin flashlight. I mean, lets face it . The only reason we cant see other solar systems too well is because its too dark out there. Some of these so called planets might just be space junk for all we know. We could also shine the light at the moon and reflect lunar light to our "solar" panels 24/7.

       Maybe consider this scenario:   

       Taking previously known information about position and trajectory of extrasolar planets (from Doppler shift observation), a powerful and focused radar beam could be used to illuminate these planets and gain additional information (like size and rate of rotation) about these planets. The return signal would arrive decades later, but it could be interesting.   

       There could even be some clever modulation of the signal to aid in the signal to noise ratio.

       One of the reason why the dark matter in our universe is so dark is that no light is there for it to reflect to us. You can make a massive parabolic mirror to direct sunlight towards areas in space, much like your flashlight. Other mirrors can be placed around other stars to do the same. They can all be focus on one spot in space for study.

       If the dark matter in our universe is so dark, does that mean that light waves don't weigh very much?
