For a Toyota built for the road and trail, LED upgrades provide the high-contrast lighting needed for better obstacle detection.

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.
