This LED kit is engineered to add a warm white 3mm LED into a clear lamp cup secured by a nylon bracket, providing a compact and tidy lighting solution for 1/18 TRX4M models such as the Ford Bronco and Land Rover Defender. The design focuses on reliable fitment, attaching directly to the original beam so installers do not need to modify the chassis with extra holes. The small form factor keeps wiring and mounting simple for hobbyist upgrades and light tuning.
