I wear a Sam browne Reflexite belt + a (10$ / 11g / 1 meter long) strip of 60 tiny led lights powered by a very small rechargeable battery.
I used tape.


It does not show on the picture but it is EXTREMELY BRIGHT.

I bought the strip here http://www.hobbycity.com/hobbycity/s...idproduct=8942
I use this battery : http://www.hobbycity.com/hobbycity/s...idProduct=6473
But a smaller battery (32g) would have been OK because the power consumption of these led lights is MAGIC :http://www.hobbycity.com/hobbycity/s...idProduct=7302
(I have a lipo charger so I didn't need to buy one)

Eric
