Would you like to never worry
about having your life depend on a single vulnerable light filament? Would you
like brighter taillight and brake light illumination so you can be much more
visible on a dark and rainy night?
Avoid the possibility of becoming
the hood ornament on a Mack Truck! Replace the original weak tail/brake light
bulb with a USA made LED conversion kit designed to fit your taillight, and
provide bright visibility without danger of burnout due to vibration or age. Not
just an LED bulb, these kits consist of a printed circuit board with multiple
Light Emitting Diodes fitted and includes complete installation instructions to
upgrade your old light to 21st Century specifications.
Choose the right kit for your build!
