A redesigned automatic lighting system for fifth wheels will soon be available from SAF-Holland, which says its ELI-te electronic lock indicator will help drivers ensure a proper coupling when they hook onto trailers.  The ELI-te fifth wheel coupling indicator includes white LED lights for the jaws-king pin area of the fifth wheel, red LED warning lights, and a long-life, application-specific electronic control module, says Bryon Redecker, product manager.  The system is self-contained except for a power cord that must be fitted to a tractor’s electrical system.  It is replacing a version introduced about 15 years ago that links to an in-cab indicator system.  For various reasons that product has not been popular, Redecker said.  Miscouplings sometimes cause kingpins to slip loose from fifth-wheels and trailer noses to fall on the ground as a tractor pulls away.  Drivers working with the ELI-te receive simple, immediate, and actionable feedback after each coupling.  When a trailer kingpin is properly coupled to an ELI-te equipped fifth wheel, four high-intensity white LED lights mounted within the fifth wheel automatically illuminate the lock jaws.  Drivers can verify that jaws have been coupled onto the kingpin.  If the coupling is not successful, the white lights stay dark and outward-facing red lights begin flashing.  A driver can then find out why the coupling is not complete.
