Perko Double Ended Festoon Bulbs - 12V, 10W, .74A - Pair

The Perko Double Ended Festoon Bulbs represent a reliable lighting solution for marine and automotive electrical systems operating on 12V DC power. These double-ended bulbs are engineered for use in cabin lights, courtesy lights, and general utility lighting applications where compact, long-life illumination is essential. Festoon bulbs are characterized by their dual contact points, allowing them to be installed in standard festoon sockets found throughout marine vessels, RVs, and specialty vehicles. The pair format ensures you have backup illumination on hand for immediate replacement when needed.

Rated at 10W with a current draw of 0.74 amperes, these Perko bulbs deliver efficient output while maintaining minimal demand on your 12V electrical system. The 3/8-inch diameter and 1-11/16-inch length specifications meet industry-standard festoon dimensions, ensuring proper fit within existing fixture housings without modification. The double-ended design eliminates the need for a separate base structure, reducing installation complexity and potential points of failure. Clear construction maximizes light transmission and color temperature consistency, making these bulbs suitable for navigation lights, reading lights, and interior cabin applications where visibility and durability matter.

Marine operators, RV owners, and automotive professionals rely on Perko festoon bulbs for their proven performance in demanding environments. The standardized 12V rating ensures compatibility with both battery-powered and alternator-supplied electrical systems common in watercraft and off-grid vehicles. Installation is straightforward—simply remove the existing bulb from your festoon socket and insert the replacement, confirming secure seating at both contact points. Keep a pair in your onboard spares kit to eliminate extended downtime caused by burned-out interior or exterior lighting, particularly during extended trips where replacement sourcing may be limited.
