This genuine OEM Hyundai dashboard light dimmer adjustment switch mounts directly into the driver-side lower cockpit dash fascia trim bezel panel. Sourced from factory vehicle interior configurations, this core electronic potentiometer regulates instrument illumination backlighting. Replacing a burnt-out or loose switch element addresses cockpit illumination flicker faults, fixes completely black speedo display faults, and restores perfect scroll-wheel tactile resistance across internal cabin electronics layout paths.

This genuine factory-stamped interior illumination rheostat paths natively into the dashboard electrical infrastructure layouts of the specific vehicle builds detailed below:

• Hyundai i10 Hatchback Generations (Typ IA / BA Platforms): SE, Premium, BlueDrive, and Go! models across 1.0L 3-Cylinder and 1.2L 4-Cylinder petrol configurations (2013, 2014, 2015, 2016, 2017, 2018, 2019)
• Hyundai Elantra Saloon Generations (MD Chassis Track Sharing): GLS, Limited, and SE trims running matching dashboard control matrix series (2011, 2012, 2013, 2014, 2015)

• Removal Precaution: Prior to extracting your damaged dimmer control module, use a plastic trim wedge tool from the rear edge of the dashboard sub-bezel. Do not pry with sharp steel flathead screwdrivers, which can easily gouge your soft vinyl dashboard surfaces or crack the delicate plastic locking retention tabs molded onto the switch body frame.
• Electrical Installation Note: Before snapping your replacement switch multi-plug pigtail closed, inspect the female receiver wire ends for loose or pin back-outs. Faulty dimmers can sometimes run hot if an aftermarket stereo or wrong dash bulb installation draws excess current. Ensure the locking connector clicks home cleanly to prevent intermittent connection failures over bumpy roads.
• Used Cosmetic Condition Note: Sourced from a running salvage donor vehicle, this interior component has been fully bench-tested and verified functional under load. Resistance scaling curve runs smooth across the entire scroll range without signal dropouts, and the night backlighting illuminates correctly. Expect light signs of use such as faint handling friction on the plastic edge margins or normal warehouse dust; adjacent dash block trims or pigtail wiring harnesses are not included.
