What Lighting System Does the 2019 Toyota Yaris iA Have?
The 2019 Toyota Yaris iA utilizes a refined lighting configuration featuring 14 distinct bulb positions. It features an extensive lighting system powered by a halogen-based setup where a single 9003 LED dual-filament bulb handles both low and high beam duties within the same reflector.
Can You Put LED Bulbs in a 2019 Toyota Yaris iA?
For a Toyota built for the road and trail, LED upgrades provide the high-contrast lighting needed for better obstacle detection. Since your Yaris iA uses a single 9003 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 H11 LED fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
