11-10 Lamps Service and Maintenance . 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. As part of the multi-point inspection, trained dealer technicians can visually inspect the shocks and struts for signs of leaking, blown seals, or damage, and can advise when service is needed. .
