Lower left marker light has been out for a while. Investigated the issue last weekend.

    Yo

Step one, replace burned out bulb... nope, not it. 

Step two, check for power... no power... look harder

Step three, discover wire harness resting on exhaust pipe burning its way through the wire harness. 

Save yourself time, trouble, and money. Inspect your wiring harness with emphasis on those in close proximity to hot systems.

Good advice, also start looking for any wiring that has been run next to the frame/cross members and check the protective wrapping for wear. Wire loom and pieces of heater hose make for good protectors on edges. Something we do in the trucking world to prevent violations.
