I just brought a OEM quality fog light for my 2010 Prius. How much to install fog light? Walser Toyota is $180, I might go ask other car dealers. If I install my own or any car garage will affect my car warranty? (I don't have tools to install my own).
Installing it yourself will not void the warranty, assuming nothing is damaged during the install. Many on here have done this install ourselves. It does not take any special tools to install and the instructions that come with the kit, the one from Prius Chat Shop anyway, are very detailed and easy to follow. Search on this forum for Fog Lights and there are several threads with a lot of reviews on the installs. Spiderman has a really good thread. Others have had third party garages install them and some list the cost to do this.
