If your vehicle’s headlight or dash illumination behaves intermittently, the Dacall replacement switch delivers a direct-fit alternative engineered to meet original equipment specifications. Designed for Cadillac Escalade (2003–2006), Chevy Avalanche, Silverado, Suburban, Tahoe, GMC Sierra, Yukon, and Hummer H2 models from the early 2000s, this switch restores lighting control functions including headlight low beam, parking lights, dome light, and instrument panel dimming.

How does this switch match my vehicle’s original part?

The Dacall switch is molded to OEM dimensions and lists cross-reference numbers so you can confirm fit before purchase. It replaces several GM part numbers and uses the same mounting and electrical pin configuration as factory units.

• Compatible models: 2003–2006 Cadillac Escalade, 2003–2007 Hummer H2, and many 2003–2007 GM full-size trucks/SUVs
• Cross-references: 15176678, 15194803, 15198374, 15206042, 15762307, 19381535
• Check appearance and OEM number to verify compatibility

What functions and controls does the replacement provide?

This unit restores primary exterior and instrument lighting controls for vehicles that use a combined headlight/dimmer switch. It offers smooth rotation and push actions for switching between off, parking lights, and low beam, plus a rotating dimmer for dash backlighting.

• Headlight low beam and parking light selection
• Dome light control functionality integrated
• Instrument panel brightness adjustment via built-in dimmer

Is the Dacall switch durable and easy to install?

The switch housing is made from heat- and wear-resistant ABS plastic for longevity under normal driving conditions, and the internal mechanism is tuned for responsive, tactile operation. Installation is plug-and-play and comes with a removal tool to simplify replacing a faulty unit.

• Material: premium ABS plastic for heat and wear resistance
• Includes one headlight switch and one removal tool for fast replacement
• No special wiring or programming required—plug-and-play connection

What should I check before buying to ensure a proper fit?

Because several GM vehicles used similar-looking switches with different pin counts or mounting types, visually compare your existing switch to the photos and listed OEM numbers. Confirm both the external appearance and the electrical connector pattern to avoid compatibility issues.

• Compare the OEM number stamped on your original switch
• Verify connector pin types and mounting positions match
• Contact support with photos if you’re unsure before ordering

It’s also suitable for restoration projects or fleet maintenance where reliable, OEM-compatible controls are required. If you drive any of the listed model years and your headlight or dashboard illumination functions are intermittent, dimmer-operated, or completely nonfunctional, this unit provides a practical repair option without complex installation.
