LED's headlights for 2016 Civic
There are some very good aftermarket LED's that maintain the beam geometry correctly that also directly fit into the projector lights that come on most 2016 Civics with no modifiation to the basic car. While they do not look the same as the factory LED's, they offer approximately equal lightng on the road for driving and are 6000 deg K like the factory LED's for appearance. You would need two sets - one set for low beam and one set for hi beam.
You can also get some great HID 5000 or 6000 deg K lights that directly install in 5 minutes and run on the factory wiring for somewhat less cost. Opt 7 makes both for reference. If you select HID's. be sure to use the AC ballasts for improved stability, color temperature, and bulb life. Hope this helps.
