Can You Put LED Bulbs in a 1999 Lincoln Navigator?

Upgrading to LED is one of the most effective ways to modernize your Lincoln's appearance and safety profile. Since your Navigator uses a single 9007 LED bulb for both high and low beams, ensure your chosen LED kit is "dual-beam" compatible. This allows the LED circuitry to mimic the two-filament design of the original halogen bulb. Don't forget the 899 LED fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
