The concept might work, but solution looks too much like a decal. It has to be integrated with the lights or it just looks cheap and pasted on.

On a side note, I wouldn't be surprised if it caused you a host of problems if you got into an accident. At the very least I could see a cop writing you a ticket for obscuring your indicator lights. I wonder if your friendly insurance company could do something even worse (anything to get out of paying a claim).
