I just found these at a local auto parts store, they are very bright and came with lots of extra wire. The red strobe light was $19.99 and the 4 white lights were $29.99 they have a number of different settings. One warning however don't use these lights on the road, someone may claim your trying to look like the police. They are mostly recommended for off road use. Mine will mostly be used as part of my security system.
