It cost exactly $200.00-four LED's at $20 each. Then 2 hours of labor at $60/hour.

Hey Guju...I had my underdash red lights done at a custom audio store. I purchased the LED's from them and they installed them as well. But I can tell you that the red LED's were installed at the top of the kick plate (below the rear seat). I did not have them installed under the front seats. That way, they would not be kicked and broken. I hope that helps!
