What happens is the fiber optic cable (ends) either get dirty (most likely) or come loose from their respective mountings. Each headlamp, corner lamp, or turn signal, (depending on model and year) has a small stub to facilitate the optic cable and rubber and brass sleeve. Generally speaking the rubber becomes brittle and cracks allowing moisture and dirt to enter the cavity where the fiber optic cable seats. Sometimes just cleaning the end of the optic and cavity along with some electrical tape over the rubber is enough to bring the light the fender luminators.PeteC said:Yes the ones at eye level on the fender next to the hood.
They may be fiber optics. When I looked closely at them I don't see any bulbs in the little lens assembly.
So how do you fix these lights?
