Can You Put LED Bulbs in a 1991 Nissan Sentra?

Upgrading to LED is one of the most effective ways to modernize your Nissan's appearance and safety profile. Since your Sentra uses a single 9004 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 LED Fog Light fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
