We adapted our old 12-volt strip light unit to instead use an array of 12-volt LEDs, to benefit from considerably lower power consumption and more importantly never needing to buy or replace a bulb ever again! As an electronics hobbyist who is not a professional but who already does their own boat DC electrics, projects like this are totally achievable but are still best left to someone who has a proficiency and understanding of 12-volt electrics. MAINS ELECTRICS IS A COMPLETELY DIFFERENT MATTER AND SHOULD NEVER BE INTERFERED WITH EXCEPT BY A PROFESSIONAL!
