These gold load resistors are often used to remove pesky brake and reverse back-up errors when you upgrade the factory bulbs to LED; LED bulbs typically draw less power than OEM incandescent bulbs which makes your vehicle think that there's an issue - Hence the error popping up on the dash. These gold load resistors simulate 8ohms at 25W, and are designed to trick your vehicle and fix draw related issues. NOTE: These gold load resistors run quite hot, and we highly recommend these installed on a metal surface and away from plastic. The rule of thumb is: 1 per side for reverse and brakes You may get away with 1 for the brake light system FEATURES Automotive grade wire insulation Potted internals to protect it from the elements SPECIFICATIONS 8ohms @ 25W Dimensions: 30mm (L) x 15mm (W) x 15mm (H) WARRANTY 2 Year Warranty INCLUDED 1 x 25W 8ohm load resistor 2 x T-Tap connectors
