The 2005 GMC Sierra 1500 is a rugged and dependable truck, but its factory interior and cargo lighting leaves much to be desired. The dome lights produce a dim, yellowish glow that barely illuminates the cab at night, making it difficult to find dropped items, read maps, or see the floorboards. The cargo light above the rear window is equally weak, offering little assistance when you are loading gear in the dark or hitching a trailer. Upgrading these lights to LED is one of the simplest, cheapest, and most satisfying modifications you can make. With just a few minutes and basic hand tools, you can transform your Sierra's interior and cargo areas with bright, crisp, white light that makes every nighttime task easier and safer.
