What's cost to install two replacement headlights.

approx 1hr labor for both. not sure of labor rate in your area

I bought the lights at Walmart and slipped the guy at the oil change place $10.00 to do it. It is also real easy to do on most cars. Mine needed the battery moved for one and I was just to lazy to do it. I watched the mechanic and the entire process for both headlights took less than 10 minutes from start to finish!
