What Lighting System Does the 2018 Toyota Avalon Have?
Lighting on the 2018 Toyota Avalon is managed by a total of 15 bulbs, covering everything from primary headlights to signal indicators. It features an extensive lighting system powered by a halogen-based setup where a single 9005 LED dual-filament bulb handles both low and high beam duties within the same reflector. This model belongs to the late years of the Avalon's 1995-2022 production span.
Can You Put LED Bulbs in a 2018 Toyota Avalon?
For a Toyota built for the road and trail, LED upgrades provide the high-contrast lighting needed for better obstacle detection. Since your Avalon uses a single 9005 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.
