Lamps
Properly working headlamps, taillamps, and brake lamps are important to see and be seen on the road.
• Signs that the headlamps need attention include dimming, failure to light, cracking, or damage.
The brake lamps need to be checked periodically to ensure that they light when braking.
• With a multi-point inspection, your dealer can check the lamps and note any concerns.
