Product Description

Backlit Rocker Switch – Fuel Fwd/Aft

This genuine Carling rocker switch labeled “Fuel Fwd/Aft” is manufactured by laser marking, NOT printing. Laser technology allows for a stunning backlight effect. It’s a great upgrade to our popular Contura II style rocker switches.

This product is the ENTIRE SWITCH combo and includes both the switch body and the labeled cover. Find the laser-etched Fuel Fwd/Aft switch cover sold separately here.

Switch Features:

• Switch Function Two-position ON-ON (SPDT) with independent lights — great for Fuel Fwd/Aft A/B.
• Stunning readability in the dark
• Independent dual lamps: Top and bottom lamps can be wired as backlights or indicators
• 7 illumination color options: warm white, cool white, blue, red, green, amber, or bright red — all available HERE

How Does the Backlighting Work?

• Laser marking lets light show only where we etch
