Full Product Description
The Hopkins 48845 model is engineered to solve the “wiring mismatch” common in many import and modern domestic vehicles. It features short-circuit protection and over-current safeguards, which act as a firewall to prevent a trailer-side electrical fault from damaging your vehicle’s expensive lighting control modules.
The unit is encased in a weatherproof, potted housing that protects the internal electronics from moisture, dust, and vibration. Its universal design includes color-coded wires that follow industry standards, making it compatible with a wide range of sedans, SUVs, and compact trucks. The converter is rated for a total of 8.0 amps per circuit for turn/brake lights and 10.0 amps for the taillight circuit, providing plenty of power for even large trailers with multiple incandescent or LED bulbs.
