Installed these "bird of prey" headlights in 30-40 minutes. Installation was very easy and everything went smoothly. It was 100% plug and play and no additional tools or parts were required. This kit (unlike many others) includes 'add a fuse' so everything is literally plugged in and powered by the OEM fuses in the engine bay. Quick installation, very high quality headlights and I recommend them to everyone on the market! I've been buying them for a while and I'm very glad I bought them. The best quality I've found!
