Most RV interiors use 12-volt bulbs in a handful of standard sizes, with 1141, 1156, 906, 921, and 194 being the most common. These bulbs appear throughout the coach in overhead fixtures, reading lights, porch lights, and utility areas. When one burns out, matching the bulb number stamped on the old bulb is the quickest way to find the right replacement.
Our selection focuses on LED replacements from Valterra, which fit the same sockets as the original incandescent bulbs but use significantly less power and run cooler. Several options are available in multipacks, making it practical to replace all the bulbs in a fixture type at once. Check your existing bulb number before ordering to confirm the correct fit.
