Depending on the setup you want, the difficult varies. If you do a quick retro using say the Morimoto minis, then its very easy. But if you get a projector that requires cutting your headlight housing and making custom mounts then it gets a littler harder.

I never realized how bright they really were till my friend was driving my car behind me. Even with the rearview mirror on the darker reflection it hurt my eyes.

Why would you enjoy flashing them? They are flashing you to let you know that your blinding them. Your "cool" HID's are actually unsafe for other drivers and you need to either get it done the right way or get rid of them. Please do every other driver on the road a favor and return to stock.
