■ Condensation build-up on the inside of the lens
Toyota lamps are vented to all surrounding environmental conditions and may
experience temporary condensation build-up that is visible from outside of the
lamp. Condensation and fogging does not indicate a malfunction of the lamp
assembly. It is normal for condensation to improve and disappea r after time
and normal driving use. Visible pools of water or large droplets are a sign of a
lamp in which the seal has malfunctioned. If this is the case o r condensation
and fogging remain after long periods of time, contact your Toyota dealer for
more information.
